These fit as expected but are thin, it did say, "mesh" in the description.I live in a very hot climate so these will be good in hot weather.Didn't like the open, front vent for your genitalia as your junk will pop out of it unless you're not very endowed then I wouldn't worry about it.(who uses the front flaps anyhow?)I can't comment on the longevity but if they last at least 6 months I'll be happy with them.
