ExoWear Socks provide the maximum thermal protection available in exposure-protection socks and are designed for multi-sport use. ExoWear Socks provide exceptional warmth when used on their own or under boots and are sure to keep your feet toasty. OMNIRED™ Infrared Technology in the socks’ fabric converts your outbound heat into infrared energy and reflects it back to your feet for thermal warmth. 3-Layer Fabric protects from the harshest elements with materials that are water repellant, windproof, breathable, quick-drying, wicking, and anti-microbial. 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 products. 3D Print on the sole gives additional grip.
