O'Neill's Hood arsenal will regulate your body's core temperature… While you regulate the line-up. 3mm UV protection Wind resistant single layer smooth skin exterior Lightweight Fluid foam single layer neoprene Thermo layer interior Adjustable drawstring face Visor blocks sun & channels water from eyes Washing instruction: Rinse with cool water and drip dry out of direct sunlight 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.
