Lightweight long sleeve base layer for trail and outdoor use.
Engineered for all-day output, the Long Sleeve Base Layer wicks fast, dries faster, and stays comfortable when the pace picks up. A slim athletic cut with flatlock seams eliminates chafe on long efforts, and thumbholes keep your sleeves where they belong on cold morning starts.
