I purchased this for my earthquake survival kit. The bag showed up clean and intact, exactly as shown in the ad. It is Molle compatible. It can barely fit one gas mask. The cm 7m czech gas mask and an israeli 4a1 civilian gas mask can fit in this bag, along with one 40 mm nato filter. The fit is very tight so be gentle but firm when placing the mask inside Be sure to place the filter inside the mask before storing mask inside. Only negative thing about this bag is the fabric inside the bag as it feels thin and it tore a bit when pulling mask out of bag. If you're on a budget, this bag is adequate enough. Hand wash only and air dry. Overall, This bag is decent for the price.Well built, strong hook and loop (velcro) pouch closures, and with the ubiquitous MOLLE! A great addition to your PAPR rig, too.N/AHolds all my jet boil coffee stuff for the fieldMy mask fits well into the bag and has ample room for the filter canister. The molle attachments are sturdy and hold well. I wish it were a darker black, it seems slightly faded and therefore kind of stands out against all of my other gear but overall very pleasedGreat product, fits the 3M 6900 series mask with sealed canisters (in package, not attached) nestled insider the mask as well. Protects mask and canisters, keeping them together ready for use. Can even sneak in a Tyvek suit and shoe covers. Has vertical AND horizontal MOLLE type webbing on back for attachment points, Front lid has both velcro and snap buckle to snug down. I keep this equipment in my cruiser trunk, for immediate use in appropriate settings - be smart, know the limitations! The 6900 series is not a 'military grade' mask, but with the appropriate filters can provide excellent protection from many harmful items. This is not a 'tactical' style set up, no drop down leg strap, I cannot comment if this bag fits other masks. Excellent value, protects the other equipment keeping it ready to go!Fits my beta-c mag perfect. I lined it with cardboard and it slips right in.Fits the CM7M well. Cover opens from the wrong side, though.
