Set yourself free from worries when you're hitting the trail with the iXS Flow Upper Body Protective Vest. This zip-on body armor gives your back an extra shield against blows with X-matter protective foam that hardens on impact to absorb hits, giving you a barrier where you need it most. As soon as the impact subsides, X-matter returns to a flexible form that moves with you while you barrel down the singletrack, care free and in control. The vest is crafted from a lightweight and breathable synthetic that keeps moisture pulling to the outside while you ride, with a next-to-skin fit that slides underneath your favorite jersey with ease. It features two pockets along the sides of the back panel, giving you a convenient stash spot for your snacks on the trail.
