I'm very happy with my Dockers.  I bought two more packs just in case the quality goes downhill, like every other brand I've had.  The cheap brands never fit me, and the last brand, Tommy Hilfiger, degraded to printing on the underwear itself and then to one size fits all (32-34, 36-38, etc), so I had to find a new brand.

I wear a 34 and these are true to size, not tight or loose anywhere.  I wear low-rise pants (30 or lower) and these fit me fine, so I'd say you can call them briefs, despite what many negative reviews have said.  I hope they don't change a thing because they're the only quality underwear out there, but I'm stocked up now, so I don't care.
