Rab Firewall Jacket - Pertex Shield Waterproof Mountain and Trekking Jacket

Description

The Rab Firewall Jacket is a technical waterproof jacket designed for mountain use, alpine trekking, and demanding outdoor activities where protection against rain, wind, and changing conditions is the priority. It combines a robust construction with an excellent balance of protection, breathability, and weight, positioning itself as one of the most well-rounded waterproof shells in the Rab range.

Constructed with a 3-layer Pertex® Shield membrane, it offers reliable waterproofing and excellent moisture evacuation during intense activity, even on long ascents or routes with unstable weather. Its design is clearly focused on real-world mountain use: adjustable technical hood, articulated patterning, underarm vents, and a structure durable enough for technical trekking, scrambling, and summer mountaineering.

Real technical performance

In real-world use, the Rab Firewall Jacket stands out specifically for offering a sense of solid protection without entering the territory of overly rigid or heavy hardshells. The 40D Pertex® Shield 3L fabric achieves a very interesting balance between durability, comfort, and weather protection.

The jacket is clearly designed for active mountain use. The underarm vents help significantly during sustained ascents, while the adjustable, stiffened hood provides proper protection in heavy rain and strong wind.

Its robust construction allows it to be used with a loaded backpack or in abrasive terrain without the delicate feel typical of other ultralight waterproof jackets.

Much more minimalist and focused on "fast & light." The Firewall is clearly more durable, protective, and versatile.

The Kangri GTX incorporates GORE‑TEX and an even more robust construction for severe conditions. The Firewall offers a more balanced weight-to-protection ratio and is generally more affordable.
