The most difficult aspect of buying any mask is not only the over all fit, but the spacing of the features. This mask is not overly tight, which means with a little pinching and pulling, I could adjust the mask to be loose in the right areas, and it lined up very nicely with my eyes (which is I think is where masks either succeed or fail). The eye holes are not too big that you see a lot of skin underneath. They are just small enough that if they aren't adjusted to be in the right place, they are a bit uncomfortable, but thats the trade off for a close fit. I was able to get it adjusted so it hung quite naturally, and my eyes fit well. The mouth is a tiny bit lower than I would like, but not bad. Was able to drink etc, easily. The trade off for it being just slack enough to adjust, is that it isn't /quite/ tight enough to respond to facial movements beyond opening mouth to drink, talk, stick out tounge etc. For example, if you smile, it doesn't really register- but thats probably normal for this kind of product. Love the long neck and shoulder flap, it helps the mask blend in and fit with/under clothing, or a body suit, with no visible skin underneath.
