The Session is the ultimate solution for warmth, fit and flexibility on a budget. New for this winter, the 4:3 model is crafted with all new Halo X2 neoprene in the upper body, our insanely stretchy and sustainable neoprene that will enable you to push your limits in the water. This combined with the Freedom Chest Zip gives maximum freedom and performance while also allowing the user to get in and out of the suit with ease.
