Innovative Celliant Infrared Technology makes this suit very unique. A combination of Celliant fabric is used throughout the suit to offer additional warmth where needed - soft high-pile fabric for extra warmth in the bodies core and low-pile fabric in the arms and legs. Together with skin-to-skin sealing from top to bottom, the Evoke is the most advanced dive suit in the market delivering unequaled warmth. This scientifically proven technology uses 13 thermo-reactive minerals woven into the fabric lining that converts body heat into infrared energy and reflect it back onto the user. Medical studies have shown that infrared energy improves the body's circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improving overall warmth and increasing your time in the water.
