Rab Firewall Jacket - Pertex Shield Waterproof Mountain and Trekking Jacket

Description

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

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

Real technical performance

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

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

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.
