BARE Ultrawarmth Men's Base Layer Top Stay Warmer, Dive Longer Don't let the cold cut your dives short. The Bare Ultrawarmth Men's Base Layer Top uses cutting-edge Celliant® Infrared Technology to help you stay warmer and more comfortable, for longer. This isn't just a base layer; it's a performance enhancer. Celliant® technology is actually FDA-determined as a heat recovery medical device. It works by capturing your body heat and converting it into infrared energy, which is then reflected back to you. This helps to increase thermal energy, boost endurance, and even speed up recovery. This top is designed for a streamlined fit under your drysuit, with minimal bulk. The 230-g Celliant® Infrared stretch fleece has a smooth outer face for easy layering, and a brushed fleece interior for exceptional warmth and moisture-wicking. Flatlock seams minimize chafing, and low-profile thumb loops make donning your drysuit a breeze. It is great to use as part of a layering system with your drysuit.
