The Burton Men’s [ak]® Helium Grid Half-Zip Fleece is the lightweight layer designed for high output days when breathability and sweat wicking matter most. It works across winter, spring, and fall, standing alone on the hike up and adding warmth under a shell when conditions change. A slim fit and stretch fleece create a low profile that layers easily and lets the body move naturally. HeiQ Smart Temp technology helps regulate body temperature through changing conditions and long efforts, while HeiQ Fresh odor control keeps things smelling better without limiting breathability. Thoughtful details like stretch thumb loops and a zippered pocket came straight from rider feedback, and the lightweight grid panels help manage sweat when the pace picks up. This go to layer brings year round versatility to splitboard tours and cool weather hikes alike.
