SkinnyBitch Airsoft shows how she made this Tacticool Reversible Facemask that you can do it yourself... "DIY tacticool reversible facemask, made out of M81 Woodland and Jägermeister fabric. If you want to make one yourself, there are plenty of patterns that you can find online ;).
This is not a medical mask, but one you can use at an airsoft event ;)."
