Jump to: Our Verdict / Features / Specifications

Exceptionally light and reliable in wet weather, this shell is built for fast-moving days when every gram and minute matters.

Rab says: 

Your go-to for year-round mountain running, this hardwearing waterproof jacket provides enduring protection for longer days out and back-to-back training runs. It’s engineered with 2.5-layer Pertex® Shield and is packed with features to keep you running through horizontal rain. Uncompromising, reliable, and impressively lightweight, it’s a do-it-all shell that adapts to any day on the trail with dark skies overhead.

Our Verdict

The Rab Downpour Trail Light 2.5L Jacket weighs just  202g (UK12) and feels purpose-built for trail running or minimalist mountain days. The Pertex Shield fabric handles wind and persistent rain well, offering decent breathability for a 2.5-layer shell. I liked the simplicity, a single chest pocket, a clean hem drawcord, and low-profile cuffs. That said, I preferred hook-and-loop closures over the extended elastic cuffs for better adjustability, especially in cold or wet transitions. The hem at the front sits noticeably high (in size large, it sits above the belt line), which may not suit everyone for pack coverage or layering.

Ideal for lightweight trail missions where reliable protection and a streamlined design take priority.
