Tough, weather-ready and breathable enough for year-round mountain use.
Rab says:
The Firewall Mountain Jacket comes into its own when the forecast threatens to disrupt your plans. Fully featured and highly protective, it uses 3-layer Pertex® Shield to deflect persistent drizzle and torrential rain, so you can keep exploring unfazed. Equipped for year-round hikes, scrambles, and mountaineering, the Firewall Mountain Jacket is a true all-mountain shell.
Our Verdict
A dependable mountain shell that’s built to take a battering, made for wet, cold, and high places where you need your kit to work hard.
The updated Rab Firewall Mountain 3L Jacket is a solid performer in prolonged foul weather. At 521g for a Medium, it’s on the heavier side for a waterproof shell, but it earns its keep with durable construction and a well-thought-out feature set. The Pertex Shield 3-layer fabric offers trustworthy waterproofing and doesn’t feel plasticky against the skin, even during long stints on the move.
The helmet-compatible hood adjusts easily, and the peak holds its shape well in the wind. The pit zips are generous, helping dump heat fast without unzipping the front. I found the articulated sleeves and overall cut comfortable, with room for layers underneath without feeling oversized.
