Performance meets comfort with the Castelli Entrata Jacket. The practical design puts a water and wind-resistant GORE-TEX INFINIUM WINSTOPPER coating on the front of our body so we can charge along wet roads with minimal moisture seeping through, and the breathable fleece back allows sweat to escape while being wonderfully warm and comfortable. With three rear pockets, we can easily stash a couple of water bottles and some energy goo to help us push through the pain and hit our weekly mileage goal.
