BLU WAVE hoods are made in the USA, using a high-quality custom order of Super-Soft, as our vendor calls it, and flexible neoprene for the main head area. This is the same comfortable neoprene we use to make our custom wetsuits which allows for different head shapes without head pressure. The Full Face Mask model is constructed with inner seal material along the neck that does not tear easily. The neckline is angled downward towards the front for a better fit. We special order the double-sided Smooth Skin seal material that is reinforced with an inner layer of nylon for the seal around the face and chin. There’s no forehead seam on the Smooth Skin face seal, only at the chin area. The chin piece has been designed to fit and form to your chin with its width of only 2 inches. Not too wide, and not too short either. The jawline has a durable Gridprene insert for structural support of the Double-sided Smooth Skin seal to press against your face. Seams are triple glued with drysuit adhesive and sealed together using a special process normally used in making commercial drysuits. Seams are then blind stitched, and bar tacked at stress points. All production of our hoods, except for the making of the neoprene material, is done here in the USA.
