Synergy Triathlon Wetsuit - Men&rsquo;s Adrenaline Fullsleeve Smoothskin Neoprene for Open Water Swimming Ironman Approved SUITABLE FOR ALL LEVELS  The Synergy Adrenaline is a swimmer's dream. It provides the buoyancy necessary, yet it feels like you are swimming in a sleeveless suit. The anatomical construction offers support where needed and keeps you comfortable at the height of performance. Ironman approved. Athlete endorsed. Comes in wide range of sizes to insure a perfect fit. PROVEN TECHNOLOGY EQUALS SUPERIOR PERFORMANCE  The Adrenaline is designed along the same feature rich parameters as the elite Synergy Hybrid with one exception. It uses hydrodynamic SCS silicone coated SyPrene in the main HiFlex panel in the torso and upper legs whereas the Hybrid uses Yamamoto AeroDome for those panels. This makes the Adrenaline more flexible and more subtle. 5mm thick core buoyancy panel / 3mm lower legs and back / 2mm arms and shoulders. EXCEPTIONAL FUNCTIONALITY  Full range of motion. Unsurpassed 680 percent flexibility. Highest grade anti corrode internal wetsuit zipper from YKK which greatly reduces drag as you move through the water. Super soft low neck with smoothskin on both sides and because it is so soft, it feels like you hardly have anything around your neck. MAXIMUM BUOYANCY - 5mm wetsuit, which is the maximum buoyancy allowed in triathlon wetsuits. Creates nearly double the buoyancy than 3mm suits, which are not recommended for cold waters. Float higher. Move faster. Save energy.
