MaineMilitary.com is having a great sale on a few of their gas masks; real cheap, up to 40% off. So if you’ve been meaning to get your hands on a mask and not sure where you get one, I suggest taking this chance up. I’ve been a costumer of them for a while now and they’re a great site to buy masks and other military supplies from. 

….aaaaand I should mention that some of their supplies is not for sale anywhere outside the U.S., sorry.
