I play airsoft in the woods around here with friends, but don't own my own airsoft gun. I'd rather borrow one from someone and spend that money on a real one

It's good fun, but you can really only play with people that are honorable enough to call their own outs otherwise you have to get right on top of them and hold the trigger down until they finally call their own out

Also, it's best to wear a full face mask as these things can easily knock teeth out or fly into an open mouth and cause serious tissue damage and I find it very hard to breathe through my mask so running between cover all the time has me constantly winded.
Do you have a better alternative for a face mask? I have a plastic full-coverage mask and can't breathe worth a damn through it.
