Women's Colorado Retro MTN Summit Aero Mesh Jersey

The Summit Aero Mesh Jersey is engineered for warm-weather performance and long-distance riding. Made entirely from lightweight stretch mesh with 37.5® active-cooling technology , it helps regulate body temperature by pulling humidity away from the skin—keeping you cooler, drier, and more efficient on every mile. (Independent University of Colorado research has shown 37.5® can increase athletic output by up to 25%.)

Mesh sleeves and a YKK Vislon semi-locking zipper provide excellent ventilation and easy, one-handed venting on the fly. A reinforced back panel prevents pocket sagging, while three full-size pockets with expanding bottom bellows offer secure storage for ride essentials. A zippered valuables pocket with a glove-friendly pull keeps cards, keys, and cash protected.

A lightweight mesh gripper hem holds the jersey in place, and powerful 350-lumen reflective accents ensure 360º visibility when the light fades.

The result: a highly breathable, fast-drying, high-performance warm-weather jersey built to go long.
