These are the most comfortable of all the briefs I've tried.  I used to buy Jockey, but since they changed (several years ago) the design on the waistband they obviously changed the elasticity, etc.. waist becomes un-usable after a couple of washes.. sometimes on opening the package they were too loose.  The leg openings were too loose, also.

These BVDs have kept their elasticity, in fact they may slightly shrink on washing, making them more comfortable for me.

Have tried other brands also.. prefer the BVDs
