The utility model refers to special diving equipment. The wetsuit is designed to protect the diver from hypothermia when it is in the aquatic environment during the operation of the equipment for full autonomy, as well as from mechanical damage to the skin during underwater works, contact with marine biological and zoological objects, during entry and exit from the aquatic environment.

Known rescue suit, containing trousers and a jacket with a collar, a central clasp, as well as a warming layer of positive buoyancy. The overalls are provided with a pelerine attached to the base of the collar and plates with positive buoyancy located in the pelerine in the knee and chest parts of the jumpsuit, said plates in the chest part of the jumpset fixed along it with successive overlapping of each other, the warming layer of the overalls trousers made of hygroscopic material [copyright certificate SU 1740244]. As noted in the description, the hygroscopic material of the warming layer of the overalls trousers gets wet and heats the legs of the person, the material with positive buoyancy keeps the human body afloat, so his head will be above the surface of the water,

A known disadvantage, it should be noted that in fact, the wet material does not store heat well, which is especially important at low water temperatures. Rescue overall does not prevent water from entering the human body, not only in the trouser area, but also through the collar and sleeves, which leads to its rapid cooling.

The closest in terms of technical essence and accepted as a prototype of a real utility model is a swimming salvage diving suit. It includes a jumpsuit made of non-elastic strong lightweight air-watertight fabric, at least one compressed air cylinder, a valve for connecting the cylinder to the floating elements of the wet suit. On the surface of the overalls, membrane seals are made of air-impermeable material, in compliance with the seam tightness requirements, connected to the cylinder valve with compressed air by means of plastic tubes [Patent of the Russian Federation No. 137541].

The disadvantage of this solution is that the sewed membranes that ensure the air-tightness of the space between the costume material and the membrane itself, ensure the buoyancy of the person only on the back, making it difficult to move in the water. A compressed air cylinder that is attached to the chest area of ​​the swimmer is susceptible to mechanical damage that can lead to a dynamic swoop attack and explosion of the balloon. The presence of the balloon leads to an increase in the weight of the wetsuit, which negatively affects the transportation and the number of rescue equipment in view of its massiveness.

The technical task of the utility model is the creation of a wetsuit capable of providing the necessary temperature regime, which excludes the supercooling of the swimmer's body, while in the water at low and negative temperatures.

A dry suit consists of a helmet 1, a coverall, a bleed valve 2, an inflatable valve with a quick-release hose 3, a cuff of sleeves 4, a neck seal 5, an intensifying cover 6, a tight zipper 7, bots 8, pockets 9, a fastex fastener 10, moisture absorption pads 11.

In Fig. 1 - the construction of a wet suit of dry type.

The technical result is achieved by the fact that a dry suit is equipped with an air supply system in the sinuses of the shell of the suit and the inclusion of special moisture absorption pads placed in places of intense sweating. In this case, the heat in the suit is preserved due to the heat-insulating properties of its material. The creation of an air gap between the surface of the human body and the external hostile environment provides protection against hypothermia, and thanks to gaskets, excessive moisture accumulates in the subcostal space, which enhances the suit's property to protect the human body from overheating. The thickness of the air gap and the thickness of the gaskets can be adjusted, which makes it possible to adjust to the temperature of the medium. Seams on overalls are airtight. Sealing of the entrance to the overalls is provided by a special hermetically sealed zipper 7, located in front in a special apron. The product is a tight-fitting airtight overall made of a fabric of the "Gortex" or "Aquatex" type, whose work to ensure the tightness of a wet suit and improve the thermal insulation properties in the product design provides the following technical solutions:

- on the product the neck obturator 5 is made;

- Cuffs 4 are provided on the sleeves of the article to ensure the tightness of the jumpsuit connection with gloves (gloves) of dry type.

To ensure the bleeding of air from the subcompartmental volume, the bleeding valve 2 is installed on the left sleeve of the product. A blow-off valve is installed on the chest of the overalls. The blow-off valve 3 is supplied by the breathing apparatus. Sealing of the cervical obturator 5 is performed with the help of a cervical cuff, which, after dressing the overalls, rolls up so that it fits snugly against the side surface.

The implementation of features of a useful model provides a technical result consisting in providing the necessary temperature regime that excludes the supercooling of the body of a swimmer when in water at low or even negative temperatures, as well as increasing the time of work in unfavorable climatic conditions, in improving the transportation process for account for reducing the weight of the product.
