NeoSport Men's Triathlon Full Suit neoprene TRIATHLON WETSUIT: Designed for flexibility, comfort and buoyancy with speed skin neoprene and ultra soft coated skin material. ADVANCED TECHNOLOGY: One of NeoSport's most advanced triathlon wetsuits to date, with lightweight Speed Skin neoprene and soft Coated Skin neoprene, provides buoyancy, flexibility, and comfort. HIGH PERFORMANCE WETSUIT: 5 MM neoprene on chest panel creates ideal positioning in water to reduce drag, and 3 MM back panel permits efficient stroke performance. SPEED: Mid-calf leg openings increase kick efficiency and decreases drag, and wider exit openings diminish heel snag, speeding up suit removal and transition times. SUPERIOR DESIGN: Range of motion is improved thanks to strategic placement of three-millimeter, Super Four-Way Stretch neoprene along shoulders and underarms for unrestricted reach.
