The Jump Fleece breaks the mold with the Oakley 3-in-one layering system. This fleece integrates perfectly with Oakley jackets that share the system technology, so your winter wear is like a second skin instead of a blubber layer. Integrates into 3-in-1 jacket systems. Cuffs with elastic for a sealed fit. Reverse coil spring-loaded zippers. 100% polyester.
