STREAMLINED, WARM AND WATERTIGHT. Diving in a drysuit means you're always warm and comfy, no matter how cold the water. Restyled for 2016, the EVERDRY 4 offers the streamlined fit, comfort and flexibility of a wetsuit, with the thermal properties and water-tightness of a drysuit. The EVERDRY 4 offers the ultimate in neoprene drysuit technology. It is constructed of 4mm high-density neoprene sandwiched between layers of nylon jersey — the heavier outside layer is designed to withstand abrasion, the lighter inside layer is more for comfort. Seams are triple-glued and double-thread blind-stitched on the outside; the inside is coated with a liquid polymer that penetrates the nylon layer and fuses to the neoprene, creating an extremely durable and waterproof seam.
