Born on the thin side but aging and measuring about 41-42" around the gut.  First time boxer user cause another type (panty?) is getting tight around the legs.  I like these very much.  Extra large just good fit, and the trunks not too long.  Stitching around the legs came off but it looks like just the edge, not the whole hem.  Bought 3 sets but should have tried the first set longer and through more washing cycles.  But so far these feel very comfortable, soft and easy on the weight gaining body.  If the stitching deteriorate further, will come back for another review.
