The Vz.35 is a Czech licensed copy of the Mk IV General Service Respirator developed by CHEMA in 1935. There was variant of this mask made in 1937 called Optimit OPT which could be connected to German breathing apparatus Heeres-Atmer KG120.

Overview Edit

The Vz.35, Similar to the mask which it derives its design from - That being the Mk IV General Service Respirator, has a Rubber Interior, and Stockinette Fabric Exterior. It has two large glass three-layered eyepieces held in place with metal rings. The intake/outtake valve is a of a simplistic design used by most early Czech masks, having two variants - The Vz. 35 "S" - Which was designed to be used with a hose, and the standard Vz. 35, the inlet valve/threads of which are at a 45 Degree angle, intended for use with Standard Filters. The mask utilizes a very basic 6 point harness system with a small rubber patch in the center, it also includes a carrying strap. The mask can come with a canvas bag for the S variant, but the regular variant uses a standard carrying can. The full set also includes a small case with a towel for cleaning the lenses.

The mask was copied by Yugoslavia, resulting in the M-2 and M-3.

The Vz.35 and Vz.35 "S" Variant were purchased from Czechoslovakia by Spain for Civil Defense Usage during the Spanish Civil War, however these Variants are virtually identical to the Czech ones, with the only major difference being Spanish variants were generally issued with a Spanish 'CMP' Filter.


There are more variants of this gas mask, for example the civilian gas mask from the year 1938 uses a TF-1A filter.

Bag and kitEdit

Gas masks were stored in metal canisters or canvas bags, those without hose didn't need so much space so tins were enough for them.
