The Flexor Hooded Vest is excellent for layering and turns any wetsuit into a hooded model. The body of the vest is made of 0.5mm neoprene lined with Magma thermal insulation our warmest, lightest yet. This thermal insulation wicks moisture from your skin, keeping you drier and warmer for longer. This vest is easy to slide under any wetsuit without too much-added bulk. The 3mm hood is made of 100% super stretch neoprene for ultimate flexibility, a sharkskin peak shields the face from water runoff and the sun.
