Bare's ExoWear Jacket provides the maximum thermal protection available in a neutrally buoyant exposure-protection garment and is designed for multi-sport use. OMNIRED Infrared Technology in the jacket's fabric converts your outbound body heat into infrared energy and reflects it back to your body 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. Zip up for warmth and protection or zip down to regulate your body temperature. This versatile piece is ideal for changing conditions and can be used on its own or added to the long sleeve top or vest.Whether diving, kayaking, or stand-up paddle boarding, ExoWear's innovative 3-Layer Fabric protects you from the harshest elements. An outer layer, membrane and inner fleece feature properties that are water repellant, windproof, breathable, quick-drying, wicking, and anti-microbial. Outer Layer: UV resistant outer layer has a durable water-repellent finish to provide a protective shell that sheds water, absorbs less water, and increases drying time. Membrane: Windproof and highly breathable membrane provides maximum comfort during high-exertion watersports and helps regulate body temperature while preventing wind chill. Inner Fleece: Microban Anti-Microbial with Hydrophobic technology and quick-dry fleece coatings mean less stink and a more easily packable suit to transport to your next destination or dive site.OMNIRED Infrared Technology applies 13 thermo-reactive minerals woven into the suit's fabric to convert outbound body heat into infrared energy and reflect it back to your hands. Infrared energy has been proven to improve the body's circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improve overall warmth and increase your time in the water. This process has been proven in strict scientific studies to outperform similar technologies. Flat seam stitching throughout with seamless underarms for maximum flexibility, stretch and comfort. 3D Pattern for optimal shape and fit. 2mm ELASTEK Full Stretch Neoprene at neck and wrist for added comfort and sealing. Binding at the hem for premium finish. ExoWear slows thermal loss by 36% at 1ATM of pressure(proven in controlled lab thermal testing).
