What Our Gearhead® Experts Are Saying: “This fleece became my go-to for uphill missions—super lightweight and surprisingly warm. I love how the thumbholes keep the sleeves in place when layering under a shell, and it breathes really well when I’m working hard.” When we need a dependable midlayer that moves with us and keeps us warm without bulk, we reach for the Oakley Drift Tech Fleece Jacket. Built with lightweight polyester and a touch of spandex, it hugs close to trap warmth while stretching effortlessly through skintrack switchbacks, quick laps, and long transitions. Whether we’re adjusting boots or making coffee at the trailhead, the thumbholes keep sleeves in place and hands shielded from cold morning air. On warmer spring ascents, we wear it solo for breathable coverage, and when winter shows up in full force, it slides under our shell like it was made to be there. Side zip pockets stash our beacon or snacks securely, and the trim fit avoids bunching under a harness or pack. It's a one-layer-does-most piece we rely on from first snow to corn season.
