Rab Men’s Downpour Pants - Waterproof & Breathable Rain Pants for Hiking & Trekking (Black, XL/32)

Overview

The Rab Men’s Downpour Pants are a dependable rain layer designed to keep you moving when a sudden shower rolls in on the trail. The shell uses Pertex Shield 2.5L, bonded to a lightweight 50D recycled fabric for a compact footprint that’s easy to stow in a pack. In real-world wear, the fabric feels featherweight against the skin, with a subtle sheen that hints at solid water resistance and steady breathability. A fluorocarbon-free DWR finish helps shed dew and mist, while the PU backing contributes to durability without adding bulk. Weighing roughly 9.3 ounces, these pants aim to balance protection with a comfortable, non-bulky fit that layers well over midlayers or base layers.

Rab’s design philosophy emphasizes responsible materials and practical features for hikers and trekkers. The 2.5-layer membrane works in tandem with a regular, gusseted cut to provide freedom of movement on steep ascents and long descents, while the full-length gusset ensures you aren’t restricted during knee flexion. Drawcord adjustments at each hem keep the pant legs snug over boots in muddy conditions, and the ¾-length side zippers offer easy venting or quick over-shoe changes in sudden downpours.
