While riding without a shirt may seem to be a viable option in the scorching heat of summer, staying covered is actually more effective. It's also easier to carry your gels and keys while wearing a shirt. The Mavic Sprint Relax Full Zip Short Sleeve Jersey keeps you covered and cool. The jersey is sewn from Wick Matrix fabric, which allows air to circulate beneath the fabric and assist in pulling moisture to the surface where it evaporates. The full length zipper enables you to dump air quickly on the long climbs. In addition to providing cooling, the fabric is also coated with Hot Ride UV finish, which has a UPF of 30. To hold everything you need for a hot ride, the Sprint Relax features five back pockets: three open, one zippered, and one mesh.
