The Core Arm Warmers bring OMM's PrimaLoft ACTIVE insulation to a lightweight stretch fleece sleeve, giving you a fast way to add warmth without stopping to pull on a full extra layer. At just 35g the pair, they're easy to carry as insurance for a cold summit or an early start, then stash away the moment temperatures climb. The 4-way stretch fabric moves with you, and flatlock seams keep them comfortable against the skin through hours of running or hiking. PrimaLoft ACTIVE continues to insulate even if they get wet, and dries quickly once conditions improve, so a sudden change in weather won't leave your arms cold for long.
