blueseventy Men's Reaction Fullsuit Black A blend of SCS coating, 2mm neoprene and our orange high stretch jersey improves arm mobility, reach and propulsion. The new Reaction benefits from 2mm thin Side Panels that begin at the arm gussets and end at the knee. This technology improves fit and body position in the water without sacrificing buoyancy. A central split chest panel allow greater chest expansion and unimpeded breathing. Over twenty years of wetsuit design experience has made our traditional zipper an industry standard. Our curved closure flap reduces rear collar height improving comfort and reducing chafing. Our tube construction in the lower leg uses a single seam to maximize the flexibility and promote a quick release from your suit in transition. Liquid taping on the internal seam reinforces and allows you to cut the leg to your desired height.
