The protective jacket model 63 was intended for individual protection of an individual against poisonous substances (liquid), radioactive substances and biological warfare agents. Its use, however, had a broader character - it also partially protected against light radiation, was used to protect against discomfort, for improvised transport over water obstacles and to set up a tent. This list shows which older elements of the individual's anti-chemical protection should have been replaced - protective clothing model 51/55, anti-chemical raincoat model 46 (made of impregnated paper), anti-chemical gloves and slippers model 50/55 and tent raincoat model 53. They introduced it to ČSLA in 1964 and went into production that same year.
The set consists of a cloak with a hood and rubber gloves. Rubber gloves are sewn into the sleeves. Everything is made of polyamide fabric coated with oppanol (polyisobutylene) and later with butyl rubber. The cloak was worn either rolled up on the back at shoulder level or in a tulmuk. It could also be used as a coverall after wrapping the lower flaps of the cloak around the legs (in the last photo). In the underarm part of the coat there is a double wall that forms two chambers. After being inflated (which is what the valves were used for), these provided the possibility of overcoming water obstacles. Two coats were needed to set up the tent.
