The BARE ExoWear Vest provides the maximum thermal protection available in a exposure-protection garment and is designed for multi-sport use. OMNIRED™ Infrared Technology in the vest’s fabric converts your outbound body heat into infrared energy and reflects it back to your body for thermal warmth. 3-Layer Fabric provides more protection. And because freedom of movement is essential in the water, ExoWear’s 4-Way Stretch provides more elasticity and breathability than the 2-Way Stretch found in similar vests. For maximum maneuverability, ExoWear Vest offers protection for your core, while allowing for maximum mobility with large arm holes. Great as a standalone product or under a wetsuit for additional warmth.
