O'Neill Womens Epic 5/4 wetsuit now comes in chest zip. Over the years Epic was our best selling wetsuit for so many reasons. Now there is another reason - chest zip which allows less leaks of water and gives you that extra flexibility.     100% UltraFlex DS neoprene High-performance super-stretch neoprene with a durable outer skin that resists velcro pulls and snags. Stretch factor: 150% Glued & Blindsticted Seam Construction The blindstitch seam is aptly named because the stitching only goes part way through the neoprene. If a suit is blindstitched, it is also glued so there is no leakage through the seams. Glued and blind stitched construction provides a waterproof seam. A blindstitched suit is also taped in all areas of excessive stress. O’Neill’s exclusive blindstitch is the Flexloc Stitch which is stronger and more flexible than the traditional blindstitch and eliminates unraveling of the seam. O'Neill's proven GBS-glued and blindstichted seam Is double-stitched partially through the surface and triple glued to create a watertight seam. If the thread breaks, the seam will not leak. F.U.Z.E. Entry system O’Neill’s exclusive F.U.Z.E. (Front Upper Zip Entry) system offers a fresh alternative. Using the same free floating zipper technology as our patented Z.E.N. ZIP closure. The F.U.Z.E. closure keeps you dry and allows unrestricted flexibility.
