At Fox we don't consider the Defend Wind just a jacket, we believe it is an essential piece of four season riding gear. Weather can change without notice on nearly any trail at any time of the year. As such the extreme packability and highly wind proof and water resistant build make it a truly necessary piece of gear for all but the hottest and dryest adventures. The ultra lightweight 50 gram Cordura(R) ripstop provides excellent durability usually only found in much more expensive jackets and the light weight and packability it offers is unmatched in the market place. Designed to pack in to itself, the Defend Wind Jacket fits into even the smallest jacket, short or jesey pocket for at the ready performance on any ride.
