Light, cool, and fantastic looking! The 4.0 jersey is the premium racing jersey made from ultra-light, stretchy mesh fabric that wicks moisture and features air channels.

The custom-fit, race-ready stretch material can be worn with or without a protective vest and is naturally suitable for use with a neck brace. The elbows of the jersey are reinforced with Brush Guards, an ultra-thin, flexible film that is featherlight and increases scratch and abrasion resistance.

Welded seams at the cuffs and hem ensure maximum comfort and fit. So just point your bike at the trail and stay loose!
