Gas Mask Carrying Case. Originally issued with the United States M17 gas mask. This bag has straps that can be configured to carry in multiple positions. Over the shoulder, around the waist strap or attached to a belt with the hooks and used with the leg strap. Great item for airsoft and paintball warriors as an ammo bag because of the ease and speed in opening/closing.

It may be marked with M17, M17A1, or M17A2 and S, M, or L for the size of mask it originally contained. Sorry, no choice.
