I bought one pair to try out for running as I've always been a loose fit boxers guy then I ordered four more as I enjoyed wearing them through out the day.

Super comfy, is a more snug and slim style so if not your style suggest go up a size

Super comfortable material and construction, like the briefs, but with a little more coverage and legs that don’t ride up.
