A pretty good buy
These seem to be well made and go on comfortably enough, but I find two issues: 1) I miss the bendable band at the top for snug fitting at top of nose, and these have the potential to slide (although I suspect when they shrink a bit from washing they will fit tighter).  2) it has two layers, obviously better than just one (which is not recommended at all), but now I'm thinking three layers even better and I wound up getting some of those that I'm happier with. My ultimate verdict: I'll keep and use these (will put 'em all in the wash first to tighten 'em up), but won't repurchase; I recommend you go for a model with 3 (or more) layers and the bendable band at top.
