A coverall-type protective/working garment sealing against the wearer's neck, arms and legs, comprises two separate layers (1, 2), of which the inner layer (2) next to the body is breathable and capable of letting through moisture/vapors (sweat) from its inner side to its outer side, and the outer layer (1) is substantially airtight, except in at least one lower region (1e) located above the leg seal, and at least one upper region (1f) located below the neck seal, in which regions the outer layer is air-permeable, such that surrounding air admitted through said air-permeable lower region (1e) to the space between said layers (1, 2) will carry along, by chimney effect, any moisture/vapors admitted by said inner layer to said space, out through the air-permeable upper region of said outer layer (1f). |
