Bold, sporty and techy—just like our favorite mountain biking trails—this moisture-wicking top delivers dynamic performance while racking up style points from big ups to burly downs.

With the performance of a tech shirt and a dose of signature style, the Shifter Shirt rolls with any ride from rowdy downhills to burly singletrack. Moisture wicking and feather light, this relaxed-fitting top stays cool on sweaty climbs and adds breathability from subtle underarm ventilating panels. Two-way stretch provides mobility on the twists and turns of the trail and UPF 50+ sun protection has you covered. For the final touches, a sunglasses loop on the chest pocket keeps shades accessible and a zippered pocket at the back hem stows small essentials.
