Hyperflex VYRL 2.5mm Chest Zip Multi-Sport Fullsuit The VYRL Series is a result of 1000's of hours of research and testing and a breakout in materials and wetsuit design. Featuring a new strain of Quantum Foam neoprene which is ultra light weight, and feverishly warm. Minimal seam design combined with insanely stretchy rubber create a performance suit that can't be touched. All VYRL suits have a quick-drying micro-fleece lining, providing a soft comfortable fit that conforms to your body.
