Technical Specifications
Waterproof. Stretchable. Ultralight.
The Ultralight Shell Pants are built for fast-moving days when you need real protection without extra weight. Using the same advanced stretch 3-layer fabric as the Ultralight Shell Jacket — developed with Toray — they provide full waterproof performance with unusual elasticity and reliable breathability. Weighing under 300 g / 10.5 oz, they pack down small and disappear in your pack until conditions change. Full-length side zippers allow easy on/off without removing shoes or boots, ideal for variable mountain weather. Articulated patterning keeps movement natural on steep climbs, traverses, and technical approaches.
