UL All-weather Pants

World's Lightest Triple-layer

When hiking a steep uphill, windy ridgeline, or in the pouring rain, this All-weather Activewear keeps you comfortable anytime, anywhere.

Our All-weather series, using the Pertex Shield Air, is significantly lighter than other conventional breathable moisture-permeable jackets and pants. The fabric’s superior breathability makes the jacket unbelievably comfortable, making it work as a windshell or as a rain jacket.

UL All-weather Pants are the world’s lightest rain pants made of three-layer nanofiber fabric. Being slightly slim, surprisingly light, and breathable, they are suitable as windbreaker pants even when sunny. A handy smartphone pocket has been newly added since 2023.

25SS Model Changes
We switched to a flat drawstring, to prevent the pants from riding down when loaded with items.
