I've gotten compliments on this jersey's versatile style both at the trailhead and at the brewery. --Gearhead Expert AlexWith its buttery soft polyester fabric and classic button-up design, the Backcountry Button-Up Long-Sleeve MTB Jersey is home both on the trail and on the town. The 4-way stretch fabric is lightweight and breathable, keeping us cool and dry wherever we ride or walk around. We also added plenty of technical features, ranging from reflective detailing for low-light conditions to UPF 30 protection for lunch rides in the sun.
