Prana is a yoga brand that's getting a little more love these days for good reason. All of its pieces have a funky vibe and are made from fabrics that feel like second skin. I'm a huge fan of these turquoise Mahdia Isis Pants ($75). The fold-over waistband is something I usually look for, and there's a back-seam calf slit that allows for easy ventilation. These pants are a great long option for Ashtanga or Bikram.
