Full and complete endorsement of the Castlegrade G9!
I'm writing this review having owned and used the Castlegrade G9 mask for many weeks now. Here are the facts: (1) The mask is very comfortable! Now, obviously not wearing a mask is more comfortable but since that is not an option in many places now, it is a fact that it is comfortable. (2) The mask provides a level of security! The straps keep it on tight (I use the neck straps which I find to be perfectly comfortable.) and there are no or minimal gaps of any kind around the edges. I don't ever feel that anything that shouldn't be entering my mouth or nostrils is doing so. (3) If you wear glasses, this mask is a MUST. Because it is tight (as mentioned above), your glasses DO NOT FOG which for me is slam dunk. I had previously had no luck using any other mask or technique to keep my glasses from fogging. I find fogged glasses to be more than a nuisance and actually dangerous in many circumstances. (4) This mask is incredibly easy to clean by simply putting it in the top rack of the dishwasher. It comes out looking and smelling fresh and clean. So I feel very confident in fully endorsing this product and I recommend it.
