YAMAMOTO HIGH DENSITY NEOPRENE Our design team has created a suit that delivers the best mix of attributes available in any drysuit on the market today. Yamamoto High Density Neoprene is hyper-compressed for optimum resistance against deep-water high-pressure compression, and the Kanako Outer Layer increases suit longevity, durability, and comfort. NO STITCH TECHNOLOGY (NST) NST makes suits without a single seam stitch. Instead, seams are double-glued and heat taped inside and out. This BARE-exclusive feature delivers superior performance and maximizes the life of your drysuit by eliminating holes in the neoprene from stitching.
