Important Features in a Dry Suit

Watertight zipper: Originally developed by NASA to hold air inside astronaut space suits, dry suits have a these special waterproof zippers to keep drysuits dry. Commonly fitted across the back of the shoulders, drysuit zippers can also be placed diagonally across the front of the torso, on the side, or straight down the middle of the front or back. They’re the most expensive part of a dry suit, but the most important to keep water out.

Wrist/neck seals: Dry suits seal at the wrist and neck to keep water out. Made of neoprene or latex rubber, these need to seals need to fit snugly without cutting of circulation, but keeping water from going in.

Air Exhaust valves: As air forms the key layer of protection between the two shells, dry suits feature valves to release air that balloons out the suit as air in the suit expands on ascent. Some modern dry suits have valves so you can add air as you descend or release it as you come up to accommodates the pressure change. Due to this feature divers need not use a buoyancy compensator (or BCD) and buoyancy control differs from wearing a regular wetsuit.
