The Body Glove Red Cell Slant Zip 5/4/3mm Hooded Full Wetsuit is designed to keep you warm and dry so you can stay comfortable during your long cold water surfing sessions. Its Red Cell lining aims to create a barrier within the wetsuit while re-directing infrared heat back at the body. This lining is most successful when the suit is as dry as possible. So, Body Glove constructed the suit with a water shedding neoprene, minimal seams with microbead sealant, and Glide Skin seals. Plus, should the suit fill up with too much water, chest and back drain holes efficiently get rid of that excess water so you can spend more time surfing in frigid waters.
