The best waterproof hiking pants complete the rain gear system that a jacket alone cannot — keeping your lower body dry during sustained rain, river crossings, and the constant wet brush contact that trail hiking in wet conditions produces on your legs and feet.
Most hikers buy a rain jacket before they buy rain pants — which makes sense because the jacket protects the core, where hypothermia risk is highest. But wet legs and wet boots create a trail experience that most hikers abandon early, regardless of how good their jacket is. Cold, wet denim or cotton hiking pants clinging to your legs for the last 6 miles of a 10-mile day is the specific misery that turns a challenging but achievable hike into a genuinely unpleasant experience.
Quality waterproof hiking pants paired with a quality rain jacket create a complete weather system that keeps you genuinely comfortable in sustained rain rather than merely surviving it. For hikers who have invested in a quality rain jacket but are still hiking in standard softshell or nylon hiking pants in the rain — this is the upgrade that completes the system.
For the complete rain gear setup, our guide to the best rain jackets for hiking covers the jacket side of the equation. And for the boots that keep your feet dry beneath your waterproof pants, our guide to the best hiking boots for beginners covers waterproof boot options at every budget.
What to Look for in Waterproof Hiking Pants
Waterproof rating determines how long they keep you dry in sustained rain.
The same millimeter waterproof rating system used for rain jackets applies to rain pants — 10,000mm handles moderate sustained rain adequately, and 20,000mm handles heavy sustained rain. The seam sealing matters as much as the fabric rating — fully taped seams prevent water entry at the stitching lines that waterproof fabric alone cannot address. Critically taped seams cover only the highest-exposure seam lines. For rain pants worn during sustained trail hiking in wet conditions, fully taped seams are the minimum standard worth accepting.
Packability determines whether you actually carry them on every hike.
Waterproof hiking pants that are too bulky to pack conveniently get left in the car when the forecast says chance of rain rather than certainty — which is exactly the condition where you discover on the trail that the forecast was wrong. Packable rain pants that compress to a stuff sack the size of a large apple or fit in a jacket pocket remove that friction entirely. You carry them on every hike regardless of the forecast because the pack penalty is negligible. When rain arrives, you put them on. That behavioral change — carrying them every time rather than selectively — is what makes packability more than just a convenience feature.
Fit over hiking layers determines whether you can actually put them on mid-hike.
Rain pants that fit precisely over bare legs or thin hiking pants cannot be pulled on over gaiters, trail runners with thick soles, or multiple base layers without removing your boots. Full-length side zippers that open from ankle to hip allow you to put rain pants on without removing your footwear — a practical necessity when rain arrives suddenly on a trail where stopping to remove and re-lace boots is impractical. Articulated knees that allow full leg extension without the fabric pulling tight are worth confirming before buying — rain pants that restrict knee flexion on steep terrain are uncomfortable and potentially unsafe.
Breathability determines whether your legs sweat as much water as the pants keep out.
Non-breathable waterproof pants trap perspiration from sustained hiking effort — your legs get wet from the inside instead of the outside. At 10,000g breathability or higher, waterproof rain pants allow enough moisture vapor to escape during sustained hiking efforts to prevent significant perspiration buildup. Pit zips on rain jackets manage upper body ventilation — rain pants typically manage lower body ventilation through ankle vents and the natural air movement that leg movement creates during hiking. Breathability matters more for rain pants worn during sustained effort than for stationary use.
The 5 Best Waterproof Hiking Pants in 2026
#1 — Outdoor Research Helium Rain Pants
Best Overall Waterproof Hiking Pants | Score: 9.3/10 | Price: ~$109
The Outdoor Research Helium Rain Pants are the lower-body complement to the Helium Rain Jacket we covered in our rain jackets guide — the same ultralight Pertex Shield fabric, the same packability, and the same genuinely waterproof performance in a pant format that weighs 4.8 ounces and packs to fist size.
Ultralight Performance That You Actually Carry
At 4.8 ounces, the Helium Rain Pants weigh less than a standard water bottle and pack into their own stuff pocket at approximately fist size — genuinely small enough to occupy the bottom of a daypack hip belt pocket without contributing meaningful weight or bulk to the pack. The 20,000mm Pertex Shield fabric with fully taped seams handles heavy sustained rain without breakthrough. The ankle zippers open wide enough to pull the pants on over trail runners and light boots without removing footwear.
The honest trade-off is the same as the Helium jacket — the lightweight fabric is less durable in heavy brush and technical terrain where abrasion contact is sustained. For trail hiking on established routes, the durability is completely adequate. For bushwhacking and off-trail travel in heavy brush, a heavier alternative is worth considering.
PROS:
- 4.8 ounces — lightest genuine waterproof hiking pants on this list
- Pertex Shield 20,000mm fabric with fully taped seams for heavy rain performance
- Packs to fist size — fits in a hip belt pocket without a meaningful weight penalty
- Ankle zippers allow on-trail donning without removing footwear
- Packability removes the behavioral barrier to carrying rain pants on every hike
- Outdoor Research lifetime guarantee
CONS:
- Higher price at approximately $109
- Lightweight fabric shows abrasion wear faster in heavy brush and technical terrain
- Minimal pockets — storage is limited compared to heavier alternatives
Best for: Day hikers and backpackers who want the lightest possible rain pants they will actually carry on every hike, particularly those whose primary complaint about rain pants is that they are too bulky to pack conveniently.
#2 — Marmot PreCip Eco Pant
Best Value Waterproof Hiking Pants | Score: 9.0/10 | Price: ~$75
The Marmot PreCip Eco Pant is the waterproof hiking pant that most seriously considered reviews recommend as the best value — genuine 10,000mm waterproof performance with fully taped seams at $75 with the same PFC-free DWR treatment that makes the PreCip Eco jacket the best value rain jacket on our list.
Honest Performance at a Fair Price
The NanoPro Eco fabric provides reliable 10,000mm waterproof protection for trail hiking in moderate to heavy rain. The PFC-free DWR treatment is environmentally improved over fluorocarbon-based alternatives. The full-length side zippers allow on-trail donning without footwear removal. The packable design stuffs into a hip pocket for convenient transport.
The breathability at 10,000g MVTR is adequate for moderate hiking effort in cool to cold rain conditions — the same limitation as the PreCip Eco jacket, where sustained high-output climbing in warm conditions creates internal perspiration buildup. For most three-season hiking in moderate temperatures, the breathability is sufficient without becoming uncomfortable.
PROS:
- 10,000mm waterproof with fully taped seams at $75 — best performance-to-price ratio on this list
- PFC-free DWR treatment — improved environmental profile
- Full-length side zippers for on-trail donning
- Packable into a hip pocket
- Marmot brand reliability is backed by decades of outdoor gear manufacturing
- Pairs naturally with the Marmot PreCip Eco jacket for a complete rain system
CONS:
- 10,000g breathability becomes uncomfortable during sustained high-output effort in warm conditions
- Less durable fabric than premium alternatives for heavy use
- DWR degrades faster than premium alternatives and requires more frequent retreatment
Best for: Hikers who want genuine waterproof performance at the best value available — particularly those already using the Marmot PreCip Eco jacket who want a matching lower-body complement at a fair price.
#3 — Columbia Watertight Pant
Best Budget Waterproof Hiking Pants | Score: 8.7/10 | Price: ~$55
The Columbia Watertight Pant is the entry point for hikers who want to test waterproof hiking pants before investing in a premium alternative — at $55, it provides the core functionality of keeping moderate rain off your legs at a price that removes all financial hesitation from trying them.
The Omni-Tech waterproofing handles light to moderate rain adequately for most casual hiking scenarios. The full-length side zippers allow on-trail donning. The packable design is convenient for packing storage. The honest limitation is performance in sustained heavy rain — the Watertight Pant begins to feel damp on the interior in heavy sustained downpours faster than the Marmot or Outdoor Research alternatives. For hikers in regions with light to moderate rain and for testing the concept of rain pants before spending more, the Columbia is a practical and affordable starting point.
PROS:
- Most affordable waterproof hiking pants on this list at approximately $55
- Omni-Tech waterproofing handles light to moderate rain adequately
- Full-length side zippers for on-trail donning
- Columbia brand reliability and wide availability for warranty service
- Packable for convenient transport
- Pairs naturally with the Columbia Watertight II jacket for a complete budget rain system
CONS:
- Performance degrades in sustained heavy rain faster than premium alternatives
- Less breathable than premium alternatives
- DWR treatment requires more frequent retreatment than premium options
Best for: Casual hikers in light to moderate rain conditions who want to test waterproof hiking pants at the lowest reasonable price before deciding whether to invest in a premium option.
#4 — Arc’teryx Beta Pant
Best Premium Waterproof Hiking Pants | Score: 9.5/10 | Price: ~$275
The Arc’teryx Beta Pant is the most technically accomplished waterproof hiking pant available at any price — Gore-Tex Pro fabric, fully taped seams, articulated knees, and Arc’teryx construction quality in a pant that pairs directly with the Beta LT jacket for the most complete technical rain system available.
When Performance Has No Upper Limit
The Gore-Tex Pro fabric delivers the same exceptional waterproof and breathability performance as the Beta LT jacket — 25,000g MVTR breathability that handles sustained high-output hiking without the internal perspiration buildup that lower-breathability alternatives create. The articulated knee pattern allows full leg extension on steep terrain without fabric restriction. The trim fit moves with your body rather than billowing in the wind.
At $275 the Beta Pant is a significant investment. Like the Beta LT jacket, it is a one-time purchase that performs correctly for 10 to 15 years with proper care, making the per-use cost lower than multiple cheaper alternatives replaced over the same period. For serious mountaineers and technical hikers who need maximum performance, the Beta Pant is the correct specification. For casual and moderate hikers, the Marmot PreCip Eco at $75 delivers adequate performance at a third of the price.
PROS:
- Gore-Tex Pro fabric delivers exceptional waterproof and breathable performance
- 25,000g breathability handles sustained high-output hiking without perspiration buildup
- Articulated knees allow full leg extension without fabric restriction on steep terrain
- Fully taped seams throughout
- Arc’teryx 10 to 15-year lifespan with proper care
- Pairs directly with the Beta LT jacket for a complete technical rain system
CONS:
- Most expensive option on this list at approximately $275
- Overkill for casual and moderate hikers who do not need Gore-Tex Pro performance
- Trim fit may not accommodate all leg shapes without sizing up
Best for: Serious hikers, mountaineers, and technical trail users who want the best waterproof hiking pants available and are willing to invest in gear that lasts a decade or more — particularly those already using the Arc’teryx Beta LT jacket.
#5 — REI Co-op Rainier Rain Pants
Best Everyday Waterproof Hiking Pants | Score: 9.1/10 | Price: ~$90
The REI Co-op Rainier Rain Pants hit a practical balance between the ultralight performance of the Outdoor Research Helium and the value focus of the Marmot PreCip Eco — delivering 15,000mm waterproof protection, full taped seams, and a more relaxed fit than the slim European alternatives at a price that makes them the most accessible full-performance option on this list.
The Well-Rounded Everyday Option
The 15,000mm waterproof rating handles heavy, sustained trail rain reliably — above the 10,000mm minimum and below the Gore-Tex Pro premium. The relaxed fit accommodates base layers and midlayers underneath without the tight feeling that slim-fit alternatives produce when worn as an over-layer. The full-length side zippers allow on-trail donning. The packable design compresses to a stuff sack small enough for daypack storage.
REI’s return policy and co-op membership discounts make the effective price of the Rainier pants lower than the listed $90 for REI members, and the REI satisfaction guarantee means the pants can be returned if they do not perform as expected in real conditions. For hikers who primarily shop at REI and want a versatile all-weather hiking pant that handles the full range of three-season conditions, the Rainier is the most practical single-purchase option.
PROS:
- 15,000mm waterproof rating handles heavy sustained rain reliably
- Relaxed fit accommodates base layers and midlayers without restriction
- Full-length side zippers for on-trail donning
- Packable for daypack storage
- REI satisfaction guarantee and return policy
- Strong value for REI members who receive co-op discounts
CONS:
- Higher price than the Marmot PreCip Eco at $90 for similar performance
- Less packable than the ultralight Outdoor Research Helium
- Less breathable than the Arc’teryx Beta at the same effort level
Best for: Hikers who primarily shop at REI and want a versatile all-weather hiking pant that handles three-season conditions without the ultralight weight penalty of the Outdoor Research or the premium price of the Arc’teryx.

Frequently Asked Questions: Best Waterproof Hiking Pants
What are the best waterproof hiking pants in 2026? The Outdoor Research Helium Rain Pants are the best overall waterproof hiking pants for most trail hikers — 20,000mm Pertex Shield fabric with fully taped seams at 4.8 ounces delivers genuine heavy-rain performance in the lightest packable format available at $109. For the best value at a lower price, the Marmot PreCip Eco Pant at $75 provides reliable 10,000mm performance with fully taped seams.
Do I need waterproof hiking pants, or are gaiters sufficient? Gaiters protect your boots and lower legs from mud and light brush contact, but do not provide the waterproof coverage from knee to waist that rain pants deliver. In sustained rain, gaiters allow water to soak the upper leg and hip area, which gaiters do not cover. Rain pants provide comprehensive lower body waterproofing from waist to ankle — gaiters provide targeted lower leg protection that supplements but does not replace rain pants in sustained wet conditions. For hiking in heavy rain, both rain pants and gaiters together provide the most complete lower-body protection.
More Questions About Waterproof Hiking Pants
How do I care for waterproof hiking pants? Wash waterproof hiking pants using a technical fabric cleaner rather than standard detergent — standard detergent strips the DWR coating and reduces waterproof performance, the same way it affects rain jackets. Tumble dry on low heat after washing to reactivate the DWR coating. When water no longer beads on the outer surface, apply a wash-in DWR treatment like Nikwax TX Direct to restore waterproofing without replacing the pants. Store loosely rather than compressed — keeping waterproof garments permanently compressed degrades the membrane and DWR coating faster than flat or hanging storage.
Can I wear waterproof hiking pants in non-rain conditions? Yes — waterproof hiking pants work in any condition as an over-layer on top of hiking pants or base layers. Many hikers wear them for brush protection, wind protection, and early morning dew contact on heavily vegetated trails regardless of rain. The breathability limitation of waterproof fabrics makes them less comfortable as standalone pants during sustained high-effort hiking in warm, dry conditions — but as an over-layer in cool to cold conditions or during active precipitation, they are comfortable throughout the full range of hiking effort levels.
