Fogs if you breathe heavily.
Stickers easily shot off.
When I got my avatar I was elated. It's a comfortable mask and is easy to clean sins the lens comes off in a manner of seconds. The reason this mask won't be getting a 9 or 10 from me is because of the fogging issue I had at the bridge of the nose where the lens clipped on to the mask. I litteraly had to line that area on the otherside of the mask in order to seal the air of from getting to the lens. I was happy after that but few months later while playing paintball the stickers on the locking clips got shot and they came of the mask, and shortly after then I noticed the foam was coming lose from the brow. This was a pretty expensive mask and it's already coming apart on me. I had to revert to my JT flex Mask in order to play properly last week since this mask looked so worn out and began to fog since the foam came off.
The vents mask is a good design, if it wasn't for the foam, the stickers, and the fogging issue I had to fix it would've gotten a ten rating, at best I'm going to have to give it an 8. If you're a big dude and tend to breathe heavily I wouldn't recommend it. If you're small and/or don't tend to breathe heavily then this mask would probably work for you. But for me back to my JT Flex Mask, I've had that for almost 2 years now and all I've done is change the lens on it.
