Bag used to carry the M 4 Gas Mask. ATF's bags are made exactly like the originals- 100% cotton canvas in od#3, Chemical Corps stencils, drain grommet in the bottom, felt pads to protect the mask lenses, 3 pockets for the spare lenses, gas sheet and repair kit, loops to hold the filter canister and anti-tinting stick, and leg strap. The shoulder strap is designed with an extra snap hook and slide to allow the bag to be carried comfortably in different positions depending on whether or not the mask was in use. Note on actual combat use: Many soldier's simply "lost" the gas mask, cut off the leg strap and used the bag for carrying miscellaneous "junk". They are a perfect size to carry on your side- smaller than a musette bag and bigger than a German breadbag. Approx. Size: 12" x 10" x 5" (30cm x 25cm x 12cm)Does NOT include gas mask, filter or any mask accessories.Made in USA, manufactured by ATF
