I Finally Gave Old Navy's Famed PowerPress Leggings a Try, and They're Worth the Hype

What's Worth Noting About These Leggings
These leggings are made of 85 percent polyester and 15 percent spandex, and, being totally honest, this combination isn't usually my go-to material for workout clothes. I prefer highly supportive and elastic nylon-based silhouettes, as opposed to the soft-textured fabric, which I personally deem more suited for lounge-worthy athleisure. Take my opinion with a grain of salt, though, as hundreds — and maybe even thousands — of people do work out in them.

Another thing to note is that the brand markets these leggings as having a high level of compression, and I can attest that they do, but for polyester. That means you won't get that same glued-to-your-body feel that you do with a nylon pair. Ultimately, it just comes down to personal preference.
