@auguste22 I ordered a medium the first time because that's what size I get my compression shorts in, but they were too tight (couldn't pull them up all the way...) on my thighs/butt so I had to send them back. HOWEVER their customer service is on point and I had my new pair back in under 5 days.
@matteosan Very tight. My buddy at the gym uses them for recovery because he doesn't like working out in compression pants, but he likes them when he's cooling down/stretching afterwards.
