The Hyperflex Flow 4/3MM Wetsuit is an awesome mid-range cold water suit that has the high-end features to keep up with the big boys. a 40/60 blend of AMPstretch super stretch neoprene/stretch neoprene keeps things warm and flexible, as does a Honey Comb HollowFiber poly fleece interior lining on the chest and back panels. The Flow 4/3 also features a shoulder/chest entry system that eliminates a back zipper that could further hinder spinal flexibility, and glued and blindstitched seams for watertightness.
