What makes a top good for mountain biking? We analyzed that through our Terry fit filter and designed the Vista. Fabric was key, so it's made of a featherweight polyester mesh that manages moisture and has superior durability and abrasion resistance for highest intensity enduro riding. Pack-friendly raglan sleeves put seams in the right place and sleeve length hits right above the elbow for good coverage. It has a sculpted hemline for ease of movement on or off the bike and a hidden zippered side seam pocket for small essentials. Semi-fitted.
