Samuel N. ★★★★★ Oct 22, 2026

The double full-length side zippers make these incredibly easy to take on and off over boots, even with thick gloves on. Wore them in a heavy downpour and stayed completely dry, while the breathability kept me from overheating on the climb up.

Madison C. ★★★★★ Oct 21, 2026

Pulled these on over my boots for a rainy alpine start—the 3-layer GORE-TEX kept me bone-dry through a full day of wet snow, and the two-way side zips made venting mid-climb effortless. Worth every penny for serious weather.

The double full-length side zippers are a game-changer when I’m layered up and need to vent fast without pulling everything off. I’ve worn them through a wet, slushy hike and stayed bone-dry the whole time, and the two-way design makes adjusting a breeze.
