I've always worn Calvin Klein boxers and I needed some new pairs so I made the purchase.  These are just like my other CK boxers but they are a little bit longer which I wish wasn't the case but it really isn't that big of a deal.  Plus, I imagine after multiple wears and washes they will shrink as I believe that's what happened to my other ones.  The waistband on these is a bit wider too which, again, isn't ideal but not that much of a big deal.  I'm still kinda surprised at what underwear costs these days but I guess you wear it every day so the cost per wear is pretty low.
