Query: Reduced Quality disappionting

I have worn these briefs and Haines for many years. The last 2 Jocky brief purchases (4 3packs) fit and wore well initially.After about 2-3 launderings, the elastic gave out and they no longer stay in place but now slide down when moving.I will not buy these until I read or hear the quality has improved.
