It's made to keep up with the demands of the pro peloton, where every watt counts. It's tested in the wind tunnel as our fastest jacket, so you know you aren't sacrificing any speed in order to stay dry. The waterproof stretch fabric fits close to the body without inhibiting freedom of movement. The sleeves are tailored to fit with gloves without adding any bulk to the wrist. We've provided three mesh back pockets to store what you might need to access quickly in wet conditions, but the mesh makes sure the pockets can't fill with water and weigh you down. On the drop tail, which provides extra protection from road spray, we've added a reflective stripe for greater visibility. We've again raised the bar for what Foul Weather Race Equipment should be.

The fabric weighs just 125gr /m2 and stretches to at least double the original dimension in each direction

The inner fabric backer is 78% polyester / 22% elastane to maintain the extreme stretch while enhancing breathability

The polyurethane membrane has been formulated to be more hydrophobic than standard polyurethane.
