Simple, lightweight, comfortable and cooling. Those are the dominant features of the Specialized Trail Air Jersey. This a great option for those who ride in the heat extended periods of time, because it does have superior wicking to keep you cool, and offers UPF30+ sun protection, but it offers just as much comfort and moisture transfer performance in humid, tree covered trails. The fit is their Regular Mountain style, so it is generous and comfortable, but not too loose or billowy when fit properly.

The Trail Air Jersey uses VaporRize™, a super lightweight, breathable fabric blend featuring recycled polyester and spandex. The piece allows air and heat and moisture out without being an exposing mesh. It is also soft and comfortable against the skin. The sleeve and shoulder are a raglan style with an upper back rear horizontal panel that keeps some structure while offering comfortable and free range of motion, with some stretch. The jersey functions well with a standard hydration pack, as well as a lumbar version. The fabric keeps you cool, protecting you from ultraviolet rays with Deflect™ UV30 protection, as well as trial side foliage. There are no pockets, seaming is minimal, and a crew neck collar feels natural and comfortable.
