I purchased these glasses because of the good value and because they have the option for an Rx insert. They look great, offer great protection, and have interchangeable lenses. They are also lightweight and offer a full field of view. After measuring the width of my face I decided to go with the ICE-2X NARO. When putting them on I noticed that there was a 1-inch gap between my face and the bottom part of the lens around the cheek area. This isn't a good thing as too much of a gap increases the chance that fragments coming from below an get in your eyes. I looked around for pictures of others wearing these and some pointed-out the exact same problem. I figured out what the problem is... the nose insert is too narrow. This is NOT specific to the NARO model as all of the models including the Crossbow use the same nose piece. It isn't like my nose is abnormally huge and wide or anything, as I said, other have the same problem and most of them just wear the glasses anyway. This isn't really a good idea because you are sacrificing protection. The nose piece is so thin that the edge catches on the bridge of the nose preventing the glasses from sitting back on your face. I noticed that when I removed the nose piece the glasses fit nicely. What ESS needs to do is create a nose-piece with better contouring to the proportions of the human nose. If you have an unusually thin nose or a very small nose (a flat face) then these might work well for you.
I ended up buying a Crossbow... these have extended lenses but still sit a bit far off my face. I am not going to try to modify the nose piece on these to provide a closer fit.
Pros: Affordable, lightweight, mutliple lens, little distortion
Cons: Nose piece is too narrow to allow glasses to sit closely to the face.
