Survivair Opti-Fit 40mm NATO CBRN 7690 Adjustable Gas Mask with Canister with expiration date 05/2017
These masks are brand new as are the filters. They are both in factory sealed packaging. However the canister, while sealed, unopened, and viable; is technically past its best use date.
This item is sold as is. Please see all photographs as they are part of the description.
