I wear contact lenses and these goggles vent well- enough to keep from fogging, but not to much to dry out or slide my lenses on the peepers. They fit good and look great too, and what's to say about the price? 15 bucks, just shut and buy em. Best buy in goggles that work.
Being someone with bad allergies and contacts, this is the only pair of goggles I've found that seals up good enough to limit the ichy eyes. The foam is wider than most and limits the "fold over". Other reviews state these limit your peripheral vision which I haven't found to be a problem. Only complaint is I wish they were a little bigger to limit them from pushing in on my eyes. Dennis Kirk never disappoints. I just wish they still sent out the paper catalogs!
