Confession: I’d never set foot inside a Costco until 2013. I’d never lived near one (the closest location when I was growing up was like, an hour away), so I’d only heard stories from other people about how you could find literally everything there, from books to jewelry to 24-packs of boneless, skinless chicken breast.

But when I went there for the first time with a friend of mine while visiting her family, never in my wildest dreams would I have anticipated finding the world’s best yoga pants.

And these aren’t even like, Lululemon yoga pants sold at a discount or anything. These are Costco’s own store brand—Kirkland—and I have never had a better, more comfortable, longer-lasting pair of yoga pants.

The boot-cut, full-length yoga pants are made out of a nylon-and-Spandex blend, with a mid-rise waistband that contains a hidden pocket. And while they look a little basic IRL, the pant fabric is thick and durable (no see-through booty here), meaning that I have had my current pair since 2015 and they have yet to rip or tear, despite wearing them multiple times per week. They stretch with you during your yoga workout, but work just as well for any person’s Thanksgiving or Christmas wardrobe. (Stretchy pants = all the more room for that second piece of pie, amirite?)

But the best part, in my opinion: They come in tall sizes. And not the usual “Visit us online for extended sizing!” nonsense that us tall women (and plus-sized women, and sometimes petite women) usually get from most stores. No—every time I’ve gone to Costco looking for these pants, I can find tall sizes in store, sitting right alongside their regular-length counterpart.

Oh, and they’re also $17. And! if you don’t have a Costco membership, you can find them online at Amazon.

Sure, there are fancier yoga pants out there with more features, and perhaps a trendier style factor. But if you’re looking for a basic, affordable pair that really stands the test of time—and comes in short, regular, and tall sizes—you can’t go wrong with these. Did I mention the second piece of pie?

Fun fact: Yoga pants are so iconic they’ve made it into a museum. And if you want to find the right fit for you, check out this go-to guide.
