I plan on waring a mask because I don't want to get a chipped tooth or a BB up my nose . (jk on the nose part), but I find a few problems...
Fogging up, how do you control this?
Hydration, how can you drink water with it on...from a tube or something maybe? Do games even last so long that you will need water?
Does mask effect hearing at all? ( i'm an Airsoft noob )
Can Paintball Mask even work for airsoft. I dont want to have my mask break on me from a plastic BB
you can very easily take a 12v mini fan (a few $ at radioshack), a small switch, and a 9v battery and wire that up (should take you all of 5 minutes) and then you can have a fan that works much the same way as a defroster in your car
you can pick up the 9v battery harnesses, some wire, the 9v, the fan, heatshrink, velcro, whatever you need at radioshack
the masks designed for paintball come in a bazillian shapes and sizes, and usually you can do pretty good just using some Fog-x or lens cleaner/anti fog stuff on the inside of the lense
although, i would much rather just use eye protection when playing airsoft, because i hate using the mask in paintball when it fogs up or gets all hot and sweaty playing speedball
