Winter’s here, but that doesn’t mean you have to give up diving and wait for the temperatures to rise. Dry-suit up and dive on! Drysuits are an amazing piece of Scuba diving gear. No more shivers, chattering teeth, skin turning blue and the loss of feeling in your hands and feet on less than tropical dives. Dry suits as the name suggests keep you dry when you’re wearing them except for maybe your head and hands. They enable divers to make more and longer dives than using a wetsuit in temperate waters and not to mention the the option to experience rarer dive sites in cold waters.
Drysuit Styles
All dry suits are full length and cover the entire body unlike wetsuits which come in options of shorties and full length wetsuits. However, drysuits are available in different materials. Neoprene drysuits are made of the same material as wet suits, except they exclude water. Shell dry suits are the more popular versions that consist of two pieces. They are loose fitting suits that provide ‘double protection’ with an insulating layer of air between the two materials. The outer part of a drysuit is a waterproof shell made from materials like neoprene, foam rubber, or a hybrid of both while the second layer is an undergarment, also made of several materials including bunting, open foam ThinsulateTM that provides insulation.
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.
Tips for Buying a Drysuit
- Unlike a wetsuit, a drysuit should be a little loose fitting on the body so you can wear clothing in it comfortably or undergarments for extra insulation, but not too loose so the air bubble inside plays havoc with your trim and buoyancy. The wrist and neck seals however, have to be snug and tight enough to keep water out without cutting off blood flow.
- Choose your undergarment when choosing your dry suit. That way you can try them both on.
- Look for drysuits with thigh pockets. These are a good thing and provide the best place to store those needed small things that you want with you on your dive. Much easier to reach than the pockets of your BC.
- Some suits feature suspenders which make it much easier to don and wear since they help keep the waist up where it needs to be rather than “baggy-ing” downwards.
- Lastly, make sure the exhaust valve of the suit is in the proper place which is usually between the shoulder and elbow, pointing straight up when you hold your arm level with your shoulder. If it’s not in the right spot, then the air won’t escape adequately as it expands, which could prove dangerous during ascents.
