Active Boxer Brief Men's F25

I've been wearing these for a week and the merino blend really keeps me cool during my morning runs. The waistband doesn't roll up at all, which is a huge improvement over my old pairs.

Finally, a pair of boxers that don’t feel swampy after a long hike—the merino blend keeps me cool and dry without that weird synthetic cling. The waistband also lies flat under my pants, which is a nice bonus.

I've been wearing these on my morning runs and they stay in place without riding up, plus the fabric dries noticeably faster than my old cotton pairs. The temperature regulation is solid too—no overheating even when I'm pushing hard.
