|I just got this mask today, and I'm really impressed. It has a great seal, the lenses are easy to see out of, and my voice can be clearly heard while in the mask. It's a great buy. The only reason it's not five bullets is because it did not include the drinking tube (I'm not positive, but I think some may?) and the NATO canister the mask is accompanied by is an older German one in the tough rubber shell, and could not be accessed in an emergency. In addition to that, it cannot be resealed once removed from the shell unless you could vacuum seal it (I cannot).
In short, it's a great mask. I just want the drinking tube and current issue NATO canisters, or 40mm sealable canisters at the least.|
