An efficient alpine shell with just the right balance of weight, function and weather protection.
Rab says:
From alpine linkups to exposed ridges, this exceptionally packable waterproof jacket is made for your tough ascents in fickle conditions. All its features have been designed to reduce bulk and weight so it’s easy to stash when clouds clear, and with 3-layer Pertex® Shield, it offers uncompromised protection when a storm strikes mid-climb. With ascent-specific articulation it’s the ideal retreat for alpine climbing, yet it also offers enduring comfort on any technical mountain pursuit in unpredictable weather, whether you’re fast hiking or negotiating knife-edge ridgelines.
Our Verdict
The Firewall Alpine 3L Jacket is a refined shell that balances mobility and protection, coming in at 334g (Medium), it feels well-tuned for fast, technical objectives. The updated Pertex Shield fabric keeps it light and compact without sacrificing waterproof performance, while still offering solid breathability. The regular fit works well over bulkier “puffy” layers, and the articulated cut moves naturally through scrambles or steep climbs.The hood is easy to adjust, featuring a stiffened peak that maintains its shape in the wind. Details like the clean cuff design and single-pull hem cinch keep the jacket fuss-free.
