Received the package, David Archy Men's 4 Pack Micro Modal Briefs Lightweight Sexy Bikinis, Micro Modal from Austria Lenzing and Spandex, tried them on, material is excellent. Put them in the wash, warm water, put they in the dryer, on low heat, so far no shrinkage. They fit a little snug around the legs opens. I then ordered the Large to see if the fit was better, they fit loose but still ok. After a long day they got loose fitting. When I order this type underwear again, Ill stay with the mediums.

For the ones that say the product is not suitable for all day wear may have the wrong size. I wear a 34 waist pants, I have a 37 hip and the medium fits good. Support for the balls is superb. The Fabric is awesome, your package will thank you. Im an average guy and they fit like you're not wearing anything. Expansion is there if you need it.
