The Blueseventy Sprint Fullsuit is known as the most comfortable, entry-level wet suit on the market. Made for triathlons, the Spring features Yamamoto neoprene for flexibility and comfort and a 3-4-4 buoyancy profile to help lift the lower body for better body positioning and less drag while swimming. That build lets us focus on our swimming--not our suit--as we strive to complete a Tri or set a new PR.
