I am very picky about underwear.  I do not buy them for sexy appeal.  I do not buy them for fashion statements or whatever.  I buy them because they are comfortable.  Boxer-briefs do not cradle, and tend to slide down, regular cotton briefs tend to stretch and bunch and if they have a fly, well, anyway.  So I like soft, stretchy, comfortable, won't shrink underwear that will fit a big guy.  These have hit on all counts so far.  Highly recommend.  Also might add that they are sized for their stretchyness, I am a big guy and will try the XL instead of the XXL as they do stretch plenty.
