A dry equipment or suit provides the user with protection against the thermal aggression of the environment by thermal insulation and waterproofing.
It’s a diving equipment, or an equipment worn by aquaculture and fishing workers exposed to the environment, cold and cold water.
A dry suit normally protects the entire body, except for the head, hands and possibly legs.
However, in “hazard” configurations full coverage and protection are provided.
The main difference between standard protective suits and dry suits is that dry suits are designed to prevent total water ingress.
This generally allows better insulation, making them more suitable for use in cold water or even at frost.
Dried suits can be double and swollen with warm air.
For divers, they add a certain degree of operational complexity, as the suit has to be swollen and deflated in relation to the depth and especially the descending or ascending speed due to the excess buoyancy factor.
Protective suits provide passive thermal protection, transferring excessive heat to the environment.
