Around Specialized HQ, this piece is called the "quiver-killer" and the prototypes have been mysteriously disappearing. In past, you had to decide whether you wanted to have a lightweight packable jacket that would protect you from wind or a not-so-packable jacket to protect you from water. Now we have created a jacket for both. Using a lightweight shell fabric and ultra-thin water-proof breathable membrane, the Deflect H2O Pac Jacket provides the protection of much heavier pieces that will fit into a jersey pocket. We added all the standard water protection features in this one: taped seams, YKK Water Guard Zippers and wrist cuffs engineered to seal water out.
