How to find the best workout leggings

Check the fabric. Synthetic performance fibers like nylon and polyester are better than cotton for workout pants because they’re often moisture-wicking, more durable, and have better stretch. Pick a smooth, shiny fabric to reduce chafing in high-impact activities like running. For studio workouts like yoga where there’s less friction, choose a soft fabric that looks matte.

Look at the construction. The seams on the inside should be flat, not raised – they’re more comfortable and help reduce irritation caused by sweat and movement. You should also make sure there’s a gusset (an extra piece of fabric in the crotch area that’s typically triangular or diamond-shaped). It prevents leggings from riding up, especially with lots of motion.

Do a DIY sweat test. Most activewear claims to be moisture-wicking, but not all fabrics passed our test. To see how it handles moisture, place a small drop of water on the inside of the legging; it should absorb quickly and spread out wide instead of beading up.

Make sure they’re not see-through. Try on the leggings in bright light for best results. Bend your knee deeply; if you can see your skin through the fabric, it’s not fully opaque. Check again in a few months because fabric can thin out or fade over time.
