Everyone's got a favorite pair of underwear, and we're betting our Boyfriend Hipster will be yours. Why? A low-rise silhouette is both sexy and comfortable, perfect for pairing with an oversized tee when it's time to hit the hay, then wearing under jeans when the sun's up and you gotta walk the dog. On top of that, they're breathable, moisture-wicking, and sustainable as all get-out.
