I've always been a cotton underwear kind of guy.  That is until I discovered Modal.  Putting these underwear on was like putting on a soft worn t-shirt that you never want to take off.  The material is soft and supple, yet supportive without being binding.  I love the way they feel and it's almost as though you're wearing nothing at all.  I have had other boxer briefs that fit so snug I felt as though I was wearing tight jeans.  Those are the kind you don't forget you're wearing.  Not a fan.
