I have about 3 pairs of Gap (non-stretch) not sure how good the stretch ones are but no issues with them. Think BR has them too (wait for sale)
Unbranded denim. 3 pairs...although the crotch is going and I didn't wear them nearly as long as the Gap ones which are perfect
You have to wait for sales for some of the bigger brands, they're usually $100 during boxing day/black friday.
Good place to check Hr2. I alway see discounted selvedge denim there.
