Product details
Product details
The Nimbus Shell Jacket is our most advanced all-season shell – engineered to handle demanding mountain weather while staying soft, quiet, and comfortable enough to wear all day. Designed as a true do-it-all outer layer, Nimbus protects you from wind, rain, and snow without the stiffness and bulk often found in traditional hard shells.
Crafted from a custom-developed waterproof and windproof membrane with high breathability, the Nimbus Shell Jacket keeps you dry on the outside while efficiently releasing excess heat and moisture during high-output activities. Fully taped seams, water-resistant zippers, and a durable water-repellent (DWR) finish provide reliable protection when conditions turn harsh.
Unlike many technical shells, Nimbus is made from a soft, flexible fabric that moves naturally with your body and packs down easily into your backpack. Two-way underarm ventilation zippers allow quick temperature regulation on steep ascents, while adjustable cuffs and hem ensure a precise, secure fit. The helmet-compatible hood and protective collar offer added coverage in exposed terrain.
From stormy summit pushes to long days on the trail or ski touring in variable conditions, the Nimbus Shell Jacket is built to adapt. Versatile, thoughtfully designed, and uncompromising in performance – this is the shell jacket we always wanted, and the one we reach for when the weather is unpredictable.
