What is the best pair of yoga pants?

Considering most women shop, travel, hike, run errands, pick up their kids from school, and lounge in their yoga pants, it’s essential to have a few pair. Companies like LuluLemon and Exhale Spa make pants that are both exceptionally flattering and extremely functional (and flexible).

But if I’m doing an Ashtanga series or strenuous poses—as opposed to just wearing my pants for a light workout and then going to the post office and picking up a latte afterward—my go-to pair are Stonewear Designs’ Rockin’ Capri ($70). Unlike lots of companies, which simply sew two pieces of cotton-polyester blend together and call it a yoga pant, Stonewear Designs, which was founded in Boulder in 1996, specializes in yoga clothing.

The Rockin’ Capri is made out of quick-dry supplex, nylon, and lycra. And while those three fabrics don’t immediately scream “comfort” like cotton does, Stonewear figured out a way to make this pant feel like a second skin. Plus, there’s no elastic at the waist to bunch up and make your belly feel bigger than it already is. On the left leg, there’s an unobtrusive pocket that’s just big enough for a driver’s license, credit card, and a few bills in case you have to fill up your car on the way home after class. I love the just-below-the-knee Capri length, but if that’s not your style, try the Rockin’ Short ($49) or the Rockin’ Pant ($70). My only complaint: The center seam, which rises from the groin to the belly button, looks a little bit like a zipper.

Since every good yoga pant comes with a matching tank, also consider Stonewear’s Tulip Top ($42). With princess seams, a built-in Coolmax bra, and dual criss-cross straps in the back, this tank can handle the most extreme stretches. My favorite color, in honor of Halloween, is Persimmon/Brownie—to match my Brownie Capris, of course.
