The Endless Cycle Windbreaker (Coaches Jacket) is made from waterproof nylon fabric with snap front closure. *The nylon fabric is 100% waterproof... However, we call this Jacket Water Resistant because the seams are not waterproof, and features a snap front closure. If you stand in the rain for hours, some water may eventually get in through the seams or the snap front closure. It also features the PCP Endless Cycle logo screen printed full size on the back and smaller on the front left chest. The ink used is highly reflective so is great for visibility while night jamming on your chopper.
