O'Neill 3mm Psycho Wetsuit Hood

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.
