but that could be said about a fair few masks.. but i see what you mean.the edge of the mask has got really straight edges, which make me feel it'll be away from your face - in the chin / lower lip area - not good - i like my i3s as they're really tight so i don't think i can get nailed in the chin, but with those grills .... oooohhh could end in tears - by the way i'm basing this arguement ENTIRELY on one the image i've seen of the mask..... so i'm probably wrong...
