These are GREAT!  Used to loose-fitting, cotton boxers ... and these are amazingly wonderful. Bought the Platinum line.  Didn't purchase this on Amazon, and someone posted a response as though they were me.  But I've edited their nasty review and actually have something to say about SAXX because coincidentally bought a pair when passing through a small town in Idaho and honestly, will continue to purchase these - most likely from Amazon!  They fit perfectly and 'stay with you' instead of bunching up.
