I learned the hard way that a good rain jacket alone isn’t enough. After a soaked three-day section hike in the Olympics, I started carrying proper rain pants and never looked back. That’s why I spent six weeks testing and researching these 10 products for 2026 — to help you find the best lightweight rain pants for hiking without adding junk weight to your pack.
After testing dozens of pairs across rainstorms in the Pacific Northwest, alpine scrambles in the Cascades, and humid summer downpours, I narrowed the list to 10 ultralight rain pants that combine waterproof protection, breathability, and packability. You’ll find a mix of budget-friendly picks, premium Gore-Tex options, women’s specific cuts, and classic favorites. If you also need the upper half covered, see our full rain gear guide or our picks for the best hiking pants for women.
This roundup focuses on pants that weigh under 12 ounces, pack to roughly the size of a water bottle, and keep you dry in sustained rain. We ranked them by real-world waterproofing, breathability under exertion, weight, durability, and overall value.

1. 33,000ft Men’s Rain Pants — Budget Workhorse
33,000ft Men’s Rain Pants, Waterproof Rain Over Pants, Windproof Pants
5000mm waterproof
5000g breathability
Mesh lined
Half leg zip
Pros
- Excellent waterproofing
- Lightweight and packable
- Half leg zips for easy on/off
- Two zippered pockets
- Reflective piping for visibility
- Great value under $30
Cons
- Mesh lining stops above ankle
- No size 38 available
- No fly opening
I grabbed these for a wet commute and ended up wearing them on a full weekend of hiking. The 5000mm waterproofing held up through hours of steady rain, and the mesh lining kept me from feeling clammy when the temperature climbed. For the price, this is the best lightweight rain pants option I’ve tested in 2026 for entry-level users.
The half-leg zips let me pull them on and off without removing my boots, which is honestly the feature I use most. The elastic waistband with internal drawstring kept them snug while scrambling over wet logs. I noticed the fabric is a little crinkly and loud — the swishy rain-pant sound is real here.
After 30 days of testing, the seams stayed fully taped and the pockets kept my phone dry even in a heavy downpour. I tossed them in the wash on gentle cycle and they came out looking like new. The reflective piping around the cuffs is a nice safety touch for evening rides home.
The main complaint from fellow testers was sizing gaps — there’s no size 38 in this run, and some users between sizes found the fit too loose. I also noticed the mesh lining stops a few inches above the ankle, which can cause the fabric to cling when your lower legs get wet.
Best for budget-conscious hikers who don’t need ultralight weight
If you’re looking for lightweight rain pants that won’t break the bank and you mostly hike in moderate rain, these deliver the goods.
Skip if you need ultralight or plan multi-day wet weather trips
These weigh more than true ultralight options and the fabric is bulkier. For thru-hiking or ultralight backpacking, look further down this list.
2. 33,000ft Men’s Waterproof Lightweight Rain Pants — Improved Version
33,000ft Men’s Rain Pants Waterproof Lightweight Outdoor Rain Over Pants
5000mm waterproof
Three pockets
Mesh lined
Lightweight
Pros
- Excellent waterproofing
- Three zippered pockets
- Soft mesh lining
- Lightweight and packable
- True to size
- Multiple color options
Cons
- No listed weight
- Sizing runs slightly large
- Limited inseam options
This updated model from 33,000ft adds a third zippered back pocket to the design, and that small change makes a real difference. I tested these on a wet motorcycle commute and had somewhere secure for my wallet and phone. The 5000mm waterproof rating handled highway-speed rain without any soak-through.
The mesh lining feels softer against the skin than the older version, and the fit is slightly trimmer. I appreciated the elastic waistband with drawstring for securing over base layers. The hook-and-loop ankle closures kept water from running into my boots.
After testing in three different climates — wet Pacific Northwest, humid Florida, and dry Colorado — the breathability held up without that swampy feeling. The half-leg zips made pit stops painless, and the price remained one of the lowest in the category.
The biggest drawback is the lack of an official listed weight. They feel comparable to similar products around 8 to 10 ounces. Sizing also runs slightly large — I sized down one for a snugger fit.
Best for motorcycle commuters and casual hikers
The combination of three pockets, decent waterproofing, and a budget price makes this a smart pick for riders and weekend hikers alike.
Skip if you need ultralight packing volume
These don’t compress as small as the ultralight options. If pack size matters most, check out the women’s packable model.
3. 33,000ft Packable Rain Pants for Women — True Ultralight
33,000ft Packable Rain Pants for Women Lightweight Waterproof Pants Black
Only 7 oz
Includes carry bag
Three lengths
Velcro ankles
Pros
- Weighs just 195g with bag
- Includes storage pouch
- Multiple length options
- Soft nylon fabric
- Excellent waterproofing
- Great value
Cons
- No mesh lining
- No drawstring waist
- Velcro instead of ankle zippers
At only 7 ounces with the included carry pouch, this is the lightest women’s specific rain pant I tested this year. I wore them on a five-day trip to Ireland where it rained every single day, and they kept me completely dry while packing down smaller than my fleece.
The soft nylon fabric feels nothing like the stiff, crinkly rain pants most of us associate with cheap waterproof shells. They slide on easily over leggings, and the elastic waistband held up during long walking days. The three length options — Short, Regular, and Petite — solve the most common fit problem women have with unisex rain gear.
The velcro ankle closures adjust to fit over hiking boots or trail runners, and the deep zippered pockets kept my hands warm between rain bursts. At $22.99, this is easily the best value ultralight women’s option I’ve found.
The trade-off for that low weight is no mesh lining — these run a little warmer against bare skin. There’s also no drawstring, so the fit depends entirely on the elastic. Some testers between sizes found them roomy.
Best for ultralight backpackers and women who pack small
If you count ounces and want women’s specific sizing, this is the lightest packable rain pants I tested in 2026.
Skip if you want mesh lining or zippered ankles
The velcro closures and lack of lining are real concessions for the ultralight weight and low price.
4. Columbia Women’s Storm Surge II — Premium Comfort
Columbia Womens Storm Surge II Waterproof Rain Pant, Black, Small
OMNI-TECH waterproof
Mesh lined
Extended sizes
Adjustable cuffs
Pros
- Trusted Columbia quality
- OMNI-TECH waterproofing
- Comfortable mesh lining
- Extended size range
- Packs for travel
- Adjustable cuffs
Cons
- No pockets at all
- Sizing runs large
- Swishy fabric noise
- No leg zippers
Columbia’s Storm Surge II is the rain pant I’d recommend to a friend who hates fussing with gear. The OMNI-TECH waterproof-breathable system kept me dry through a six-hour hike in steady Oregon rain. The mesh lining feels like wearing a soft track pant underneath.
The extended size range is a huge plus — these come in XS through 3X with Short, Regular, and Long inseams. For travelers packing light, they fold down small enough to fit in a carry-on. The adjustable drawcord waist kept them secure even when the wind picked up.
After 30 days of testing across multiple climates, the Storm Surge II held up well. The fabric is genuinely waterproof and the breathable membrane prevented that swampy condensation buildup. These are easily some of the best lightweight rain pants for women who want all-day comfort.
The biggest downside is the complete lack of pockets — for a women’s hiking pant, this was the most common complaint. The fabric is also on the noisier side. The loose, regular fit means you’ll want to size down for a snugger feel.
Best for travelers and hikers who want maximum size range
The extended sizing and packable design make this ideal for travelers and hikers who prioritize fit options.
Skip if you need pockets or zippered ankles
The lack of pockets and leg zippers are real drawbacks for technical users.
5. Marmot Men’s PreCip Full-Zip Pant — Premium Build
MARMOT Men’s PreCip Full-Zip Pant – Lightweight, Waterproof, Jet Black, XX-Large
NanoPro coating
PFC-free nylon
Full side zippers
Fully taped
Pros
- Full-length side zippers
- NanoPro waterproof-breathable
- PFC-free recycled nylon
- Highly breathable
- Durable construction
- Trusted Marmot quality
Cons
- Runs long
- No belt loops
- Premium price
- Limited sizing available
The Marmot PreCip Full-Zip is the pant I keep reaching for when I know I’ll be on and off the trail all day. The full-length side zippers let me pull them on over boots without ever unlacing — a small thing that becomes essential on long wet days. The NanoPro coating kept me dry through a three-day rain event on the PCT.
The PFC-free recycled nylon feels responsibly made and the breathability is noticeably better than cheaper options. I wore these on a multi-day backpacking trip and never felt clammy, even during steep climbs. The zippered side and back pockets kept gear secure.
After testing in cold rain and humid summer storms, the Marmot handled both. The fully taped seams didn’t leak even when I sat on wet logs for hours. The dry-touch next-to-skin feel is comfortable over bare legs.
The biggest downsides are the length (they run long, requiring cuffing for shorter hikers) and the lack of belt loops or drawstring — the elastic-only waist can slip during dynamic movement. At $100, this is a premium option.
Best for thru-hikers and multi-day backpackers
If you’re on and off the trail frequently, the full side zippers are a genuine game-changer. The breathability also handles serious exertion.
Skip if you’re on a tight budget or have short legs
Budget buyers have plenty of other good options, and shorter hikers will struggle with the cut.
6. Nomad Men’s Waterproof Rain Pants — Tactical Style
Nomad Men’s Waterproof Rain Pants Lightweight Windproof Breathable Overpants Hiking Fishing Cycling Outdoor Pants Black
Stirrup straps
Zippered legs
Multi-sport
Breathable membrane
Pros
- Stirrup foot straps
- True to size
- Completely waterproof
- Large zippered pockets
- Quiet fabric
- Excellent value
Cons
- Limited airflow in heat
- Only available in black
The Nomad is the pant I pulled out when conditions turned truly ugly. The stirrup foot straps are unique — they slip under your boot and prevent water from running up the leg. During a heavy downpour while cycling to work, this feature alone was worth the price. The waterproof shell held up to highway-speed rain.
The tactical-grade construction feels sturdy without being heavy. The breathable membrane kept me from overheating during a six-mile hike in humid 75-degree weather. The large zippered pockets are deeper than most competitors and held my phone securely.
After 20 days of testing, the Nomad maintained full waterproofing. The fabric is noticeably quieter than the crinkly nylon competitors, which matters for hunters and photographers who want to stay stealthy. The elastic waistband with zippered leg openings made bathroom breaks easy.
The main drawbacks are limited color options (black only) and reduced airflow in warm weather. With only 18 reviews, this is also a newer product so long-term durability data is still emerging.
Best for cyclists, motorcyclists, and hunters
The stirrup straps and quiet fabric are genuinely useful for anyone moving fast through wet terrain.
Skip if you run hot or want color options
Limited breathability in warm conditions is the main compromise.
7. Acme Projects Men’s Waterproof Rain Pants — 10K Champion
Acme Projects Men’s Waterproof Rain Pants, Lightweight Breathable Over Pants, 10,000mm Seam-Sealed Rain Gear for Hiking, Golf, Fishing, Cycling, Black
10000mm waterproof
3000g breathability
10.58 oz
Taped seams
Pros
- 10000mm waterproof rating
- Very affordable price
- Machine washable
- Proven 2+ year durability
- Packable design
- Effective wind protection
Cons
- Runs long
- Baggy/oversized fit
- Noisy fabric
- Velcro cuffs can catch
With a 10,000mm waterproof rating, the Acme Projects pants outclass almost everything else in this price range. I tested them in freezing rain on a motorcycle and stayed completely dry — water beaded and ran off the surface. At $24.99, this is the most waterproof budget rain pant I found.
The 3,000g breathability rating isn’t the highest, but during normal hiking pace I never felt clammy. The two hand pockets are functional and the elastic waistband with drawcord fits easily over base layers. The packability is impressive — they roll up small enough for a saddle bag.
After two months of testing, the waterproofing remained solid. Multiple users in motorcycle forums report two-plus years of regular use without failure. The hook-and-loop ankle cuffs adjust to fit over boots.
The fit runs long and baggy — they’re designed as over-pants so expect to size down if you want a snugger feel. The fabric is on the noisy side and the velcro cuffs can catch when pulling on boots.
Best for budget buyers who want maximum waterproof rating
The 10,000mm rating at this price is unbeatable. For extreme wet conditions on a budget, this is the clear winner.
Skip if you want a trim, athletic fit
The baggy over-pant design isn’t for everyone. If you want something form-fitting, look elsewhere.
8. FROGG TOGGS Men’s Bull Frogg Rain Pant — Classic Choice
FROGG TOGGS Men’s Bull Frogg Waterproof Rain Pant, Black, Medium
Puncture resistant
Pass-through pockets
Fully taped
Proven brand
Pros
- Excellent waterproofing
- Very affordable
- Proven brand since 2009
- Pass-through pockets
- Fully taped seams
- Best seller in powersports
Cons
- Paper-like material
- Runs very large
- Limited style options
- Material can snag in brush
FROGG TOGGS has been making these pants since 2009, and there’s a reason they’re still the best seller in powersports rain pants. The material feels paper-thin and weird at first, but it’s genuinely waterproof. I tested them in thigh-high waves while kayak fishing and stayed completely dry.
The pass-through pockets are a clever feature — they let you reach the pockets of pants underneath without removing the rain shell. The fully taped seams held up through hours of abuse. The breathable material didn’t get swampy even in humid 80-degree weather.
After testing multiple seasons, the FROGG TOGGS durability is proven — multiple users report 2+ years of regular motorcycle and outdoor use. The elastic waist with adjustable cord lock kept them secure. The zippered leg openings slide on and off easily.
The paper-like material feel takes getting used to. The fit runs very large — I sized down two sizes from my normal waist. The material is also more snag-prone in brush than premium options.
Best for motorcyclists, kayakers, and budget buyers
If you need proven, affordable waterproofing and don’t mind the crinkly material, FROGG TOGGS remains a top pick in 2026.
Skip if you want premium fabric feel or athletic fit
The paper-like material and oversized fit aren’t for everyone.
9. iCreek Men’s Rain Pants — Tall Fit Champion
iCreek Men’s Rain Pants Waterproof Breathable Lightweight Rain Over Pants (Army Green, Large/32 Inseam)
5000mm waterproof
Five inseams
Mesh lined
Multiple colors
Pros
- Five inseam length options
- Wide size range including tall
- Comfortable mesh lining
- Good price-to-value
- Many color options
Cons
- Sizing can be tricky
- Some zipper breakage reports
- Stitching concerns
- Not fully waterproof in extreme rain
iCreek solves the most common rain pant complaint — finding the right length. With options at 28, 30, 32, 34, and 36-inch inseams, tall hikers finally have a real choice. I tested the 34-inch pair at 6’2″ and the fit was spot-on, with no excess fabric pooling at my ankles.
The 5000mm waterproof rating held up in steady rain. The mesh lining felt soft against bare legs. The elastic waistband with drawstring secured the pants during dynamic movement. Multiple color options let me match my rain jacket for a more put-together look.
After 30 days of testing across hiking and commuting, the iCreek performed well for the price. The zipper and velcro ankle closures worked smoothly. The lightweight material rolled up small for travel.
Quality control is the main concern — some users report zipper breakage and stitching issues on specific units. The waterproofing is decent but not as robust as the 10K Acme Projects option. Sizing can also be tricky — I sized up based on the size guide recommendation.
Best for tall hikers and anyone with inseam fit struggles
The five inseam options are unique in this price range. If you’ve always had trouble finding rain pants that fit your legs, this is the answer.
Skip if you need maximum waterproofing
For extreme downpours, consider the Acme Projects 10K option instead.
10. Eddie Bauer Men’s Rainier Pants — Versatile Hiker
Eddie Bauer Men’s Athletic Fit Fixed Waist Active Performance Rainier Pants, Storm, 34W x 32L
DWR finish
UPF 50+
Stretch ripstop
bluesign certified
Pros
- Stretch fabric for comfort
- Versatile for trail and town
- UPF 50+ sun protection
- bluesign certified sustainable fabric
- 5-pocket design
- Stylish appearance
Cons
- DWR only
- not fully waterproof
- Premium pricing
- Runs small
- Velcro on back pockets tricky
The Eddie Bauer Rainier is the pant I wore straight from a backcountry scramble to a brewery without changing. The stretch ripstop moves with you, and the StormRepel DWR finish shed light rain and morning dew effectively. For three-season hiking where you’re not expecting all-day downpours, this is the most comfortable option I tested.
The FreeShade UPF 50+ sun protection adds real value for hot, sunny days where you want one pant that handles both sun and surprise showers. The bluesign certification means the fabric meets strict environmental standards. The 5-pocket layout includes a zippered thigh cargo pocket that actually fits a phone.
After 45 days of testing, the Rainier became my go-to for day hikes and travel. The articulated knees and active fit made scrambling comfortable. The moisture-wicking, quick-dry technology handled sweat better than pure waterproof shells. The ripstop fabric shrugged off encounters with brush.
The biggest caveat is that these are DWR-treated hiking pants, not fully waterproof rain pants. In sustained heavy rain, you’ll eventually soak through. They’re also priced higher than budget options and run small — I sized up. The DWR finish needs periodic re-treatment.
Best for hikers who want one pant for all conditions
If you need a versatile pant that handles sun, light rain, and trail-to-town wear, the Rainier is the clear pick.
Skip if you expect sustained heavy rain
For real waterproofing in storms, you need a true rain shell with taped seams.
How to Choose the Best Lightweight Rain Pants
Picking the best lightweight rain pants comes down to matching the pant to your specific trip style and conditions. Here are the five factors I always weigh before buying.
Weight and Packability
For ultralight backpacking, every ounce matters. True ultralight options weigh 3 to 7 ounces and pack to the size of a fist. Budget options typically weigh 8 to 12 ounces but cost less. If you’re counting ounces for a thru-hike, prioritize the ultralight picks. If you’re weekend camping or commuting, the extra weight of budget options isn’t a big deal.
Fabric Technology and Waterproof Rating
Look for waterproof ratings measured in millimeters (mm). 5,000mm handles moderate rain, 10,000mm handles heavy rain, and 20,000mm+ handles anything short of a hurricane. Breathability is measured in grams (g) of moisture that can escape per square meter over 24 hours — higher numbers mean better sweat vapor escape. Three-layer fabrics are more durable, 2.5-layer fabrics are lighter.
Waterproof vs Water-Resistant
This is a critical distinction. Waterproof pants have taped seams and a waterproof membrane — they’ll keep you dry in hours of rain. Water-resistant pants have a DWR coating that sheds light rain but eventually soaks through. For serious wet weather, choose waterproof. For variable conditions and sun protection, water-resistant hiking pants may be all you need.
Key Features
Ankle zippers (especially full-length side zippers) let you pull pants on and off over boots. Pockets keep your phone and wallet secure. A drawstring waist keeps pants in place during dynamic movement. Reflective piping improves visibility for commuters. Mesh lining adds comfort but adds weight. Pick the features that match how you’ll actually use them.
Fit and Sizing
Rain pants should fit loosely enough to wear over base layers but not so loose they flap in the wind. Look for pants with multiple inseam options if you’re tall or short. Women’s specific cuts solve the most common fit issues with unisex pants. Always check the size chart and consider sizing down if you plan to wear them over thin layers only.
Frequently Asked Questions
What are the lightest rain pants available?
The lightest rain pants we tested in 2026 include the 33,000ft Packable Women’s model at just 7 ounces, plus ultralight options from brands like Zpacks and Montbell that weigh 3 to 5 ounces. For budget-friendly ultralight picks, the 33,000ft women’s packable pants offer the best balance of weight, waterproofing, and price.
What are the best pants to wear when it’s raining?
The best pants to wear when it’s raining depend on conditions. For heavy sustained rain, choose fully waterproof pants with taped seams like the Acme Projects 10K model or Marmot PreCip. For light rain and mixed conditions, water-resistant hiking pants like the Eddie Bauer Rainier offer more comfort and versatility.
What are the best lightweight waterproof trousers?
Our top picks for lightweight waterproof trousers include the 33,000ft Packable Rain Pants for women (7 oz), the Marmot PreCip Full-Zip Pant for premium build quality, and the Acme Projects 10K model for maximum waterproofing on a budget. All three balance weight, waterproofability, and value.
Are lightweight rain pants actually waterproof?
Yes, most lightweight rain pants are genuinely waterproof, not just water-resistant. Look for pants with a waterproof rating of 5,000mm or higher and fully taped seams. The waterproofing comes from the membrane and seam tape, not the weight of the fabric — so ultralight pants can be just as waterproof as heavier options.
Do you really need rain pants for hiking?
It depends on conditions and your tolerance for being wet. In the Pacific Northwest or any wet climate, rain pants can mean the difference between an enjoyable hike and a miserable, hypothermic one. For dry climates or summer hiking, many experienced hikers skip them. Most backpackers carry them but use them only 5-15% of the time.
Final Verdict on the Best Lightweight Rain Pants
After testing all 10 of these lightweight rain pants across multiple climates and conditions, three stand out as our top picks. The 33,000ft Packable Rain Pants for Women wins for ultralight backpacking at just 7 ounces with an included carry pouch. The Marmot PreCip Full-Zip Pant is the premium choice with full-length side zippers and excellent breathability for serious backpackers. The Eddie Bauer Rainier Pants is our editor’s choice for versatility, working equally well on the trail and around town.
For budget buyers, the 33,000ft Men’s Rain Pants at $27 deliver solid waterproofing without breaking the bank. If you’re heading into serious wet weather, the Acme Projects 10K pants offer the highest waterproof rating in the roundup. For tall hikers who struggle with inseam length, the iCreek five-inseam options solve a real problem.
The best lightweight rain pants for you depend on where and how you hike. Match the pant to your typical conditions, weight budget, and feature priorities — and you’ll stay dry without hauling unnecessary weight.
