Rab Men's Firewall Pants – Waterproof, Breathable Shell for Hiking & Climbing (Black, M/32)

The Rab Men’s Firewall Pants deliver rugged weather protection designed for alpine trails where rain, wind, and mist are part of the daily routine. Built around the Pertex Shield 3L shell, these pants balance a robust waterproof barrier with breathable comfort to keep you moving through changing conditions. On misty ridges or sun-dappled approaches, they compress neatly into your pack when the weather clears, staying ready for the next ascent.

Compact, lightweight, and ready for action, the pants combine a 40D recycled nylon fabric with a durable PU coating. The result is a protective layer that resists abrasion from rocks and brush while remaining surprisingly packable. A true on-trail companion, they aim to shield you from elements without slowing you down, letting you focus on technique, balance, and route choice rather than gear fuss.
