I purchased the black cotton boxer briefs. The different colors have different amounts of cotton vs spandex and what ever.
They look and feel great when you first put them on, but after an hour or so, they lose their shape and get really baggy. I might as well have just bought boxer shorts. They lose their support and fit.

I was looking for a more flattering fit from Calvin at this price.  Would not buy again.
The Cotton stretch line is much better.
