The best black gym leggings are a closet staple—they hide sweat, marks and stains much better than pastel-colored ones do. The good news is there are countless pairs to choose from, with prices starting at just $20. The best pair of leggings will feel like a second-skin, flatter your figure and hold up to sweaty workouts. But how do you know if the pair you’re eyeing is right for you? Look for a fabric that’s soft and moisture-wicking, and consider if they’re available in a range of sizes. Also, check resale apps like Depop and Poshmark to see what people have experienced with the brand you’re considering—not just whether or not they fit as expected but how well they hold up after lots of wear.

Commerce Editor Erika Reals put these leggings to the squat test, and found them true to size with plenty of stretch (despite being made of 50-percent recycled fabric). They’re thick enough for a high-impact workout but breathable, with a wide waistband that hugs and smoothes the silhouette. And they’re a great choice for yoga and pilates, with a high-waisted design that supports the abs.
