MeUndies are a good value compared to other premium boxer briefs of this style. The modal fabric is comfortable and clings well but isn't binding. No riding up with these briefs! They are nice and smooth feeling too so no bulges under your clothes.
The narrow waistband isn't too bad and doesn't cinch although narrow waistbands can do that. (lately I have been preferring thicker waistbands like on Tommy Johns or Comfortable Boxer for this reason).
I would order a size up on your normal size as they run just a touch small. Medium fits me and that's m y usual, but a large I think would be better and won't feel bulky since they are stretch and form fitting.
