Limited line of vision. Though it would have some cool elements for lets say a short term milsim thing (breach a room, man with mask uses a *chemical weapon* breachers die) and definitely for a photo shoot.

Fixed that for you.

my first idea was to get a cactus hobbies s10 i guess i'll stick with that? or are they horrible aswell haha

It's like running around with a plastic bag over your head.

Doing anything with any gas mask on fucking sucks. You'll do it for maybe 5 minutes and then want to burn the thing.

Honestly, when I first saw frame resistant, I thought they were 'snagproof', then I saw their reference to "Normex" then knew it was Chingrish........

Yeah thats pretty much what its like. Wearing a CBRN suit or the gas mask is one thing, but both and you'll drop like 10 lbs in a game just on pure sweat and thats if your just sitting around doing nothing.

Although...call me a nutcase but before I go on course I usually run for 20-30 minutes with my gas mask on after my workout. I'll do that like a month or two before course. Its brutal, don't do it for airsoft.
