2025 Burton AK Helium Fleece Half Zip

Skin it, Boot it, or Just go for a Hike

Winter, spring, or fall, the men's Burton [ak] Helium Grid Fleece Half-Zip is designed for high-output activities where sweat-wicking and breathability are a must. From split board tours to cool-weather hikes, it's the light, go-to layer that can stand alone on the hike up, add warmth under a shell, and offer year-round versatility.

Low-Profile for Easy Layering
A slim fit and stretch fleece make for a low profile that layers easily and lets you move naturally.

Built-in Climate Control. The Living Lining® with HeiQ Smart Temp reacts to your body temperature, accelerating moisture wicking when you're hot and retaining warmth when you're cold for balanced comfort all day long.

Stink Less.
The sustainable odor control of HeiQ Fresh keeps it fresh without limiting breathability.

Small Details Make a Big Difference
Thoughtful details like stretch thumb loops and a side zip pocket come from rider feedback. Midweight grid fleece panels increase breathability and manage sweat when you're hiking or working hard.

Low Environmental Impact
Bluesign® approved product uses responsibly produced materials and PFC-free DWR for a reduced impact on humans and the planet during manufacturing.
