Predator Drysuit Dry Core Technology is revolutionizing cold water surfing. This revolutionary drysuit technology eliminates the cold freeze, chill and excess buoyancy found with traditional cold water wetsuits. Streamlined: The form fitting outer skin is made with 0.5mm super stretch micro neoprene. The outer skin forms a wrinkle free streamlined surface for fast swimming and incredible mobility. This stretchable outer layer also squeezes out excess trapped with-in the dry core reducing buoyancy for easy duck dives. Unlimited Range of Motion: The combined thickness of both layers (dry-core and outer skin) averages at approximately 1mm. The two independent layers offer an unlimited range of motion unparalleled by modern cold water surfing wetsuits. Breathable Dry Core: The Dry Core bladder is 100% water proof when immersed, however it breathes while above surface, improving comfort. No donning an ice cold wetsuit for your second session: With the Fusion just put on a fresh fleece and go. No more putting on a cold wetsuit for your second session! Huge temperature Range: The Fusion technology provides a dry barrier against the elements; however it is what you wear under the suit that keeps you warm! Just like snowboarding or skiing you match your undergarment to the conditions. Fast Dry: The Dry Core bladder will not absorb water. When wearing a wetsuit, second sessions are ruined by the torture of donning your wet and cold wetsuit. With Dry Core just shake the dry suit a few times and put on a set of fresh fleece. No more putting on a cold wetsuit for your second session! Easy to Clean and Service: The two layers of Dry Core easily separate for servicing by means of Velcro fastening tabs found at the ankles and zipper.
