Rab Men's Downpour Light Jacket - Lightweight Waterproof Hooded Shell for Hiking & Trekking | Anthracite (Medium)

Overview

Meet the Rab Men's Downpour Light Jacket, a compact rain shell crafted for day hikers and trekkers who need dependable protection without bulk. When skies look unsettled, this jacket packs down small and waits in your pack until rain starts to fall, then protects you through the next climb.

Built around a 2.5-layer Proflex membrane, it offers waterproof, breathable performance designed for active days. Rain simply beads of the surface and rolls away, while you stay comfortable during uphill efforts. The regular fit with articulated sleeves keeps your freedom of movement intact, so you can keep trekking, layering over fleece or baselayers as the temperature shifts.

Proflex protection you can feel

The ProFlex fabric delivers a smart balance of protection and comfort. It beads raindrops on contact and maintains airflow where you earn your miles, helping you stay dry without overheating on steeper sections of the trail.

The jacket incorporates essential features for moving in changing weather: a Mountain Hood that adjusts with a stiff peak to stay upright in downpours, two zippered hand pockets, and a fit that makes layering straightforward. With a medium size, you’ll notice a center back length of 29 inches and a weight around 7.7 ounces, making it easy to carry without weighing you down.
