While these underwear are durable and true to size, my qualms are with the cut around the crotch.

It seems as though these guys are cut narrowly through the crotch area, meaning that when I exercise (running, elliptical, etc) they tend to get...well...lost. Yknow?

That being said, when NOT doing strenuous exercise, they're quite comfortable and breathable. No rolling down.

Overall, four stars.
