Oneill Epic II Full 4/3mm Wetsuit Youth #3365 The 4/3mm O'Neill EPIC Fullsuit has been redesigned this year to make it function and feel like a suit costing twice the price! Made from 100% high-end superstretch neoprene, the EPIC is softer and stretchier than less expensive O'Neill counterparts. Sealed seams, a sealed neck closure, and a water resistant zipper do a great job of keeping the cold water from flushing your suit, while seamless paddle zones help you move while eliminating chafing. This is a great suit for any cool water sport.
