Featherweight Japanese performance fabric is the foundation of the Ultralight Mountain Collection — gear designed not just for the outdoors, but for seamless trans-habitation.
The ULM Jacket is an ultralight and ultra-packable full-zip hoody. Purpose-built and hyper-reduced in form. The Pertex Quantum Air fabric is wind and water resistant, highly breathable, and effortlessly layers over a tee when you need a minimal layer for run, bike, hike, boat.
Designed for mountain conditions, these ultralight pieces are massively functional in daily summer life, like stepping into a shop or restaurant where the AC is cranking, dealing with airport travel temp swings, or for just laying low underground watching the World Cup.
