The final word on cold water diving or watersports, Drysuits provide unmatched thermal protection in even the most bitterly freezing waters. Drysuits are specifically designed not just to insulate the diver, but also to prevent water from touching as much of the wearer as possible. With tight latex (or neoprene) seals at the neck, wrist, and ankle, Drysuits can be combined with Drysuit accessories like gloves, boots, a hood, and a full mask to make the suit even closer to impermeable. It's also recommended that a Drysuit be worn with an undergarment, both for comfort and for maximum insulation in cold environments.
Drysuits, while designed for extremely cold water, can be worn at most temperatures. Because they are warmer than other suits, you'll stay comfortable longer, especially when diving for long durations. Even in warm water, a Drysuit can be a fine option.
Drysuits are a complex piece of diving equipment, and require special knowledge and training. A Drysuit is not simply "a wetsuit, but better." Gas expansion and contraction means that, because of the water-tight nature of Drysuits, the air inside has to be managed. Too much air, and you gain positive buoyancy that may cause an uncontrolled, unsafe ascent with not enough time for proper decompression. Too little air, at too great a depth, and you will experience "Drysuit squeeze" as the volume of the air in the suit decreases and the suit vacuum-sucks to your skin. It is possible to add and vent air as needed, but it's a skill that takes practice. The addition of a BC (buoyancy compensator) is absolutely necessary for a safe Drysuit dive, as it can compensate not only for additional weight, but also for a Drysuit seal-failure that could lead to the buoyancy problems described above.
Drysuits also require maintenance and inspection - the latex seals at the head, hands, and feet only last one or two years before succumbing to dry rot. The seals themselves must be trimmed when the suit is first acquired - a good tip is to trim the seals down until they are about 15 percent smaller than the circumference of the limb they are going around. If your suit has neoprene seals, they ought to be stretched before us. A too-tight seal on the neck, for instance, can put pressure on the carotid artery and cause dangerous circulation problems. A neck seal can be stretched on the back end of a scuba tank overnight, and the arms and legs seals can be pulled over a tin can to get them just right.
Taking a Drysuit specialty course is the best way to ensure you know everything there is to know about such a helpful and complicated piece of equipment. There are also books, computer programs, and videos that can teach you proper Drysuit use as well.
Drysuit Packages
A Drysuit package cuts the amount of time you'll be shopping and increases the amount of time you'll be diving. Why put everything together yourself when we can do the work for you? All of the Drysuit packages listed on this page include a Drysuit duffel and waterproof zipper wax. Many of the packages contain suspenders, repair kits, Drysuit manuals, and talc powder to more easily slip hands and feet into latex seals. Others contain a full matched set of Drysuit apparel, including hood, gloves, boots, and an undergarment, sized to just what you need.
Drysuit Accessories
A Drysuit is a fantastic investment for divers of all stripes, but it is a significant investment - make sure your Drysuit lasts as long as it can, and works as well as it can, with our Drysuit Accessories. Undergarments in an assortment of styles and thicknesses are a smart investment to increase your comfort and decrease your chill. You'll need a thick Drysuit hood (5 to 7 millimeters thick) to protect your neck and head from ice cold water, and a pair of gloves and boots to keep you fully dry. A reinforced or electric Drysuit hanger can get a soaked suit dry again, preventing long-term water damage to a notoriously hard-to-dry garment. You can even find latex seal cement for repairing old or damaged Drysuits.
