I love these. I frantically pick through my underwear drawer in the morning until I find my Free Fly boxers. Not too tight, but not baggy either.

Love the company and own many, many Free Fly items. Thought I would try these. Bought a few pairs in the size recommended via the sizing chart. Not sure what the issue is, but these constantly ride up and I'm having to adjust the fit all day. From scrubs to dress clothes, the same thing happens. The material is super soft, but the fit is simply poor for some reason.

Super breathable and comfortable boxer-briefs. Already had four for the past few months, decided to grab some more! If I’m not wearing a lined breeze or reverb short, I’m wearing one of these.
