Question: do they interfere with using a scope?
Document: I have been using this mask for about a year now. While it does not fog up, the lens takes a while to remove. The mask it self is heavy and has no ear padding, so after a few hours of balling your ears and face begin to hurt. Other than that it does its job and is worth the price paid for it. All in all it is a beginner mask. The most basic mask you can find.
The mask protects you, and its cheap, but its too bulky for me. I cant see my raised scope with the mask or my iron sights. It just didn't work for me.
This product stayed true to its name. through the last couple of months through me using it it has been shot many times, both by airsoft bbs and by paintball speres and has never even slightly hurt. it is a very comfortable product to wear and because of the great  and cheap goggles it comes with you barely know you even have it on until you almost get shot in the face. i reccomend this product to entry and intermediate airsofters/paintballers alike.
I'm pretty pleased with this mask so far. I'm using it for paint-balling in ROTC. the masks they provide us with are pretty old and always fog up, so I bought my own. this mask does well with staying clear while in the field, however when I went home and tried to clean it, the experience was anything but simple. the "quick release lense system" is a joke. it literally took me about two hours just to remove the lense from these goggles. terrible.
well i ordered this mask because i play airsoft with my friends and wanted to avoid being hit in the face. the product arrived 1 day than what it was suppose to :D... its in good condition and so far i havent had any problems with it... overall: shipping was amazing and very sturdy and good product :D
used for airsoft I got shot on my jaw and this mask protected me. Not fogging, great visibility, comfortable my face don't feel warm when I'm wearing it.
this mask has a durable dense foam seal and decent viewing. bought another mask for about the same money and this one way nicer
this is amazing it protects your face but not the back so it would be a good idea to wear a hoodie as well. I wouldve got shot in the eye if i didnt have this awesome thing on.
me and my sister got paintball guns not to long ago and we wanted our dad to get one so we bought him one and it didnt come with a mask and we have this mask but paid like $20 more then what i paid for my dad's! it took a whle for them to ship it but when they did ship it i got it the next day
