Technically inclined, odor-resistant Floe™ fabric wicks and cools when temps spike during aerobic activity or elevated exercise.

High mountain, high aerobic activities demand both exceptional wicking and exceptional cooling. Our long-sleeve tech tee delivers both dynamically due to Floe™ fabric that wicks and cools more aggressively as body heat climbs to regulate temps during runs, rides or climbs. The fabric is technical but the fit is not too tight or constrictive—instead finding middle ground whether going packless or hefting a heavier load to a high point. On-seam thumbholes keep arms down, subtle drop tail adds coverage on the bike while reflective hits—in both threads and labels—add visibility. Anti-odor keeps it smelling mountain fresh.
