Kit Gas Mask Canvas Pouch

• Canvas pouch: A small, rectangular canvas pouch in olive drab (OD 7) or khaki, featuring a metal snap closure. The front is stamped with the black text "Kit, Gas Mask, Waterproofing, M1".

The M1 Gas Mask Waterproofing Kit was a standard component of the amphibious assault gear used by the US military during World War II. This kit was distributed to troops right before major beach landings—most notably during the D-Day landings in Normandy—to prevent seawater from flooding the gas mask canister and ruining the filter medium during wading operations.
