"What Our Gearhead® Experts Are Saying: ""This tee is built for high-output days on the trail. The FlashDry-Pro™ fabric in the back panel wicks moisture faster than any other tee I’ve worn, and the underarm gussets let me move freely. Whether I’m carrying a pack or pushing for the summit, the bonded seams and lightweight feel keep me comfortable the whole way up."" When the trail gets steep and the miles stretch on, the Summit High Trail Short-Sleeve Shirt keeps us cool and comfortable. This high-performance tee is designed for demanding adventures, featuring body-mapped fabric that balances weight and breathability while reducing chafing under a pack. FlashDry-Pro™ technology in the back panel actively pulls moisture away, keeping us dry even during the most intense climbs. Bonded seams add a barely-there feel, and the underarm gussets and split hem enhance mobility when we’re pushing our limits. Built for long days in the mountains, this trail-ready shirt helps us move fast, stay dry, and explore further."
