The completely redesigned Velocity builds on a strong heritage of durability and value using a selective fabric strategy BARE calls Progressive Full- Stretch – an intelligent approach to wetsuit design that results in superior comfort and performance. This latest evolution incorporates BARE's most innovative technologies, including Celliant Infrared and our unique “flip seal†seals. Celliant Infrared technology turns wasted body heat into usable infrared energy. The lining is enhanced with 13 thermo-reactive minerals woven into the fabric of the wetsuit that react to your body heat converting it to infrared energy and reflecting it back to the body increasing circulation and body warmth
