For all-weather riding, put on the super-lightweight Gore Bike Wear™ OXYGEN GT AS Jacket. With GORE-TEX Stretch inserts, raglan-cut, and an ergonomically shaped collar, the Oxygen GT AS will hug your upper body so you’re aerodynamic and comfortable during highly aerobic activities. The extremely breathable GORE-TEX® Active Shell allows your skin to breathe properly so moisture doesn’t build up. The long back keeps water from splashing up onto you from below. The jacket has a partially elastic waist. A zip at the forearm with mesh inserts makes it easy to change out of the jacket and you can also allow more ventilation in when you need it. There are reflective GORE logos front and back and reflective print on the sleeves for safety.
