Poland went back to its roots in 1967 by bringing back elements of its famous M1931 Helmet, and combining it with their Wz.50 helmet, inspired by the Soviet SSh-40. This heavy duty steel helmet is affordable, and downright cool!
The liner was updated to this weird looking one in 1975. Although it appears strange, it's one of the most comfortable liners I've worn. This helmet served Poland faithfully until the mid-late 1990s and was their last steel helmet.
Conditions will vary, and expect use. That being said, you won't receive a piece of crap.
