Like the Defeind Wind Jacket it was designed alongside, we believe this sleeveless version 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 nearly any MTB adventure around the globe. The ultra lightweight 50 gram Cordura(R) ripstop provides excellent durability usually only found in much more expensive styles and the light weight and packability it offers is unmatched in the market place. Designed to pack in to itself, the Defend Wind Vest fits into even the smallest jacket, short or jesey pocket for at the ready performance on any ride.
