Light insulation, seamless comfort, and full-arm coverage in a long-sleeve base layer for colder conditions encountered in late fall and early spring.

It’s crucial that our upper body gets an added boost against the elements during those cold fall and early spring conditions. As a solution, we developed the Spring/Fall LS Skin Layer, which has taken the torch from our iconic Skinfoil base layers with a completely revamped design and all-new blend of fibers. To start, we’ve lowered the weight by about 8% and used a tubular knit technology that’s free of irritating side seams.
