Our EZ Stretch suit is now built with an amazing new concept in neoprene; Nano Technology. As noted in Random House College Dictionary, "Nano" is "a combining word meaning very small; in units of measure, it is equal to one-billionth. ▪ "Nano" neoprene has tiny capsules in "nano" size applied over the surface of the closed cell neoprene. This allows the neoprene to repel water and retain heat, and when combined with titanium, will keep you up to 55% warmer than regular neoprene. ▪ SCS (Super Composite Skin) Titanium Metal keeps you warmer by reflecting warmth back toward your body. It does not absorb water so it dries quickly between dives, and is easy to get on and off. ▪ EZ Stretch features 4-way stretch of up to 70% over regular neoprene and provides extreme comfort and extra freedom of movement. It is warm and very durable with strong abrasion resistance, and will continue to be the most comfortable wetsuit you have ever worn!
