Scuba Diving Drysuits

Scuba Diving Drysuits allows the diver not only to stay in the water for longer, but also to experience rarer dive sites - which are, not surprisingly, the colder ones.

The loose fitting scuba diving drysuits provides a 'double protection' insulating with a layer of air. The air that fills its comes from your scuba diving tank via an outlet specially designed for this purpose. A release valve provides the outlet and the presence of air inside your drysuits therefore requires more attention to buoyancy than a wet, tight fitting one. The operating process requires a short course to master the various technicalities involved.

Scuba diving drysuits seal at the wrist and neck with the added feature of a zipper that keeps the water out and contain special inner garments that form part of the crux of the purpose of the drysuits itself. These are designed in accordance with how deep you want to dive in a similar manner that the millimeter thickness of a the suits provides the correct insulation against water temperatures and depths.

Diving drysuits to use in cold conditions is a major investment for most divers. You are not just investing in keeping dry but also in keeping warm during underwater. To do this it must fit well with seals that are efficient at the neck and wrists.

The former keeps you warm due to the thickness of the foam although the foam does compress during descent becoming thinner the deeper you go. As it becomes thinner it also becomes less buoyant so air needs to be put into the drysuits to compensate for this.

A membrane of diving drysuits is usually made from a trilaminate material and is purely for keeping the water out so an undersuit has to be worn for warmth. As you descend, the air in your suits becomes compressed and seems to shrink - this is known as suit squeeze - so air needs to be put in to maintain neutral buoyancy and also to prevent "squeeze". The air added to its warms up by body heat and acts as an extra insulation layer; this effect is reduced the more the drysuits is compressed.

Bear in mind that with a neoprene drysuits you need to counteract the effect of squeeze and the material compressing. There are a couple of types of material that blur the boundaries between membrane and neoprene; - crushed and compressed neoprene. These have the toughness of neoprene but without the tendency for the suit material to alter it's buoyancy during the dive but it is more expensive than standard neoprene or trilaminate suits.
