Abstract

A protective hood (1) made of an elastic, elastomeric, gas-impermeable material, with a head area (2) and a neck area (4) joining the head area (2) with its top end (3), is to be improved such that good seating of the protective hood is achieved at different head sizes. This object is accomplished by the protective hood (1) being made in one piece according to the dipping process by means of a plate-shaped mold, the material of the protective hood having an elongation at tear greater than or equaling 600% and a modulus 100% of 0.15 to 1.3 N/mm.sup.3, and that with the protective hood (1) folded up flat, the greatest width (10) of the head area (2) is 250 mm to 340 mm and preferably about 287 mm.
