Best Waterproof Hiking Pants for 2026

The Arc'teryx Gamma MX is the benchmark for premium softshell hiking pants, and after a full Pacific Northwest autumn of testing in rain, sleet, and wind, it earned that reputation. The Fortius DW 2.0 fabric is a 4-way stretch softshell that feels almost like athletic wear on the trail — there's no crinkle, no restriction during high steps, and the articulated patterning allows a full range of motion that most hardshell pants can't match. Yet it sheds light to moderate rain reliably, with water beading and running off during our 45-minute rain tests without any damp-through sensation.

The DWR treatment is supplemented by a wind-resistant face fabric that adds a layer of protection in exposed alpine conditions. Full-length side zips are one of the Gamma MX's most practical features: they allow you to vent aggressively during hard uphill sections without removing the pants, and they make it possible to pull the pants on and off over boots — a small but genuine convenience on variable-weather days. The zips run from ankle to mid-thigh and have AquaGuard waterproof zipper tape to prevent any seepage.

At $325, the Gamma MX is one of the most expensive pants in this roundup, and the honest assessment is that you're paying for fit, finish, and the Fortius fabric's combination of stretch and weather resistance that Arc'teryx has spent years refining. There's no meaningful equivalent from other brands at this performance and mobility level. If you hike frequently in mixed conditions where rain can start and stop throughout the day, this is the pant you'll reach for every time.

Outdoor Research's Foray Pants occupy a compelling middle ground between softshell comfort and hardshell weather protection. The AscentShell 2.5L membrane is OR's proprietary electrospun waterproof-breathable fabric — it's not Gore-Tex, but in back-to-back rain tests it performed within 5% of premium Gore-Tex products in waterproof ratings while offering noticeably more breathability at aerobic effort levels. That breathability matters enormously when you're hiking uphill: most waterproof pants trap sweat badly on sustained climbs, but the Foray stayed noticeably more comfortable during our 2,000-foot test ascents.

Three fully functional pockets — two hand pockets and one internal map pocket — are a practical advantage that budget rain pants consistently omit. The hip pocket placement is specifically designed to remain accessible when wearing a backpack hip belt, which is a detail that shows genuine design thinking for actual trail use. Full-length side zips run from ankle to upper thigh and have watertight snap closures at the top to prevent gape.

At 12 oz and packing to roughly a softball, the Foray is an ideal backpacking rain pant. The fit is streamlined without being tight, and the gusseted crotch adds mobility on technical terrain. This is the pant we'd recommend for someone who hikes 20+ days a year across varied weather and wants one pair that handles everything from light drizzle to sustained downpours.

The Marmot PreCip Eco is a genuine waterproof rain pant at a price that's hard to argue with. The NanoPro 2.5L construction is fully seam-sealed with critically taped seams — not spot-taped like some budget competitors — which means there are no weak points for water to find during sustained rain. In our downpour testing (measured at 1.5 inches per hour) the PreCip kept legs completely dry for 60 minutes of active hiking, performance that would cost twice as much from most brands.

The 'Eco' designation refers to the PFC-free DWR treatment — Marmot reformulated this pant to eliminate perfluorocarbons, which are persistent environmental pollutants, without sacrificing meaningful waterproof performance. The trade-off is that PFC-free DWR treatments currently deplete slightly faster than traditional PFC-based treatments, meaning you'll reapply spray-on DWR a bit more frequently after the first season. This is a minor inconvenience, not a dealbreaker, and the environmental improvement is substantive.

The zip-off leg option converts the pants to hiking shorts in under 30 seconds, which is a real convenience on variable spring and fall days where temperature swings of 20°F between morning and afternoon are common. The pants are a bit roomier through the hip and thigh than performance-fit models, which improves comfort for a wide range of body types but creates slightly more fabric bulk when zipping into waterproof gaiters.

The Fjällräven Keb Trousers represent a completely different philosophy from membrane-based waterproof pants. The G-1000 HeavyDuty Eco fabric is a 65% polyester / 35% organic cotton blend that's inherently wind-resistant and highly abrasion-resistant, with weather resistance provided by Greenland Wax impregnation rather than a membrane laminate. You can adjust the weather resistance level by applying more or less Greenland Wax — wax it heavily for full rain protection, or use minimal wax on dry summer trips for maximum breathability. This system has been Fjällräven's approach for decades, and it genuinely works.

The construction details are exceptional for the price. Reinforced seat and knee panels use a double layer of G-1000 where the fabric sees the most abrasion — sitting on rocks, scrambling, kneeling on trail debris. Seven pockets including two large thigh pockets provide genuine storage capacity without the pockets flopping open. The fit is substantial through the hip and thigh — clearly designed for all-day comfort on the trail rather than gym-style aesthetics — and the articulated knees allow a full range of movement on steep technical sections.

At 19 oz and $399, the Keb Trousers are the heaviest and most expensive pants in our test group. They're not the right choice if you're trying to shave grams on a long-distance thru-hike. They're the right choice if you want a pair of trail pants that will outlast multiple seasons of hard use, perform across a wide temperature range from cold alpine to warm valley, and look appropriate in a trail town restaurant. We've seen pairs of Keb Trousers that are 10+ years old and still going strong.

Columbia's OutDry Ex technology takes an unusual approach to waterproofing: instead of laminating a membrane to the inside of the outer fabric, the membrane is bonded to the outside of the inner fabric layer, with the outer fabric sitting on top as a protective shell rather than a waterproof barrier. The practical result is that there's no outer DWR coating to degrade — the membrane itself is the outermost waterproof layer. During our testing this translated to consistent waterproofing even after multiple washes and extended outdoor exposure where traditional DWR-treated garments typically start to wet out.

At 10 oz the OutDry Ex Reign is the lightest fully waterproof pant in our roundup, and it packs to smaller than a softball — ideal for stowing in a pack hip belt pocket as an emergency rain layer. Full side zips run from ankle to hip and the waist adjusts with an internal drawcord. The fit is relaxed enough to wear over base layers in cold conditions while remaining streamlined enough to avoid catching on brush.

The $140 price point is where this pant makes its strongest case. You're getting OutDry Ex's membrane-forward approach — which genuinely addresses the DWR degradation problem that plagues most waterproof pants — at about half the price of Arc'teryx or Outdoor Research. It's not as breathable or stretch-friendly as the premium options, but for hikers who want reliable waterproofing on a real-world budget, this is the smartest value buy in the category.
