Most wetsuits and dry suits use neoprene, a synthetic rubber that is waterproof,insulated and flexible lycra, a type of nylon, is used in thinner suits. These aremore flexible, but most appropriate for diving in warm and shallow waters.The inside and outside of wetsuits and dry suits typically have a nylon fabric laminatedto the neoprene. This helps resist tearing and abrasion. We use different stitching techniques to increase the seal at the seams. These are usually glued and stitched or glued and taped. A well fitting wetsuit increases insulation and comfort. They should fit snuggly but shouldn't restrict your movement or breathing. If a suit is too loose, you allow water to enter, defeating its purpose. A wet suit should be sized similar to your regular clothes, so our wetsuit can be tailored-made.
