Smarter Than Your Average Fleece

Skin it, boot it, or just go for a hike. The women's Burton [ak] Helium Power Grid™ Full-Zip Fleece layers easily, dumps heat on the uphill, and delivers warmth on the way down. The pack-friendly design is wind and weather resistant on the front with an extra-breathable panel on the back. It's that go-to layering piece that can stand alone on the hike up and feels great under a shell, too.
