What Our Gearhead(R) Experts Are Saying:"I wear this for everything from cold trail runs to early winter hikes, and the ActiveTemp treatment actually keeps my head from overheating once I get moving. The close fit means it never slips out from under a hood."Multi-sport cold weather days demand a beanie that can keep up with shifting effort levels, and the Trail Mix XT Beanie is built for exactly that kind of versatility. ActiveTemp technology regulates warmth as the body heats up on a climb or cools down at a rest stop, while a close-to-head fit stays snug through a run, a hike, or a day spent moving between both. UPF 50+ protection adds a layer of sun defense for high-elevation days, and the stretchy recycled polyester knit folds into a simple cuff that stays comfortable whether it's an early morning trail run or a slower afternoon hike.
