 A neck seal, wrist seal, manual vent, inflator, zip and fabric of a neoprene dry suit. The soft seal material at the neck and wrists is made from single backed closed-cell foam neoprene for elasticity. The slick unbacked side seals against the skin. The blue area is double-backed with knit nylon fabric laminated onto closed cell foamed neoprene for toughness. Some insulation is provided by the suit, and the rest by garments worn underneath.

Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene.[1] Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of commercial applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation, medical gloves, liquid and sheet-applied elastomeric membranes or flashings, and automotive fan belts.[2]
