Product InformationFickle sunshine, variable temperatures, and horizontal rain: shoulder season hiking calls for packable waterproof protection you can rely on. Constructed using durable 3-layer Proflex fabric, the Firewall Light Jacket withstands abrasion from your pack straps while being lightweight, supple, and quiet to wear. The knitted backer fabric is soft next to skin, so its comfy when worn over a tee, but also easy to layer on cooler days. Lightweight and taking up minimal space in your pack, the Firewall Light Jacket offers all-day weather protection for any mountain adventure, from your weekend hikes to hut-to-hut treks.
