What Our Gearhead(R) Experts Are Saying:"I keep this cinched around my neck on windy trail runs and pull it up over my nose the second a gust hits. It's become the one piece of gear I never leave in the car."Wind that cuts across an exposed ridge doesn't care whether it's hitting a neck, a face, or an ear, and the Trail Mix XT Ubertube is built to cover whichever one needs it most. A simple adjustable draw pulls the fleece tube snug for extra coverage on the worst gusts, then loosens back into a relaxed neck warmer once the trail drops back into the trees. ActiveTemp technology keeps the fabric from trapping too much heat as effort builds, and UPF 50+ protection adds sun defense for high-elevation days, making this a single piece of gear that adapts as fast as mountain weather does.
