Thoughtfully designed from concept to production, this boxer brief is our take on a modern, upgraded base layer. We've paired performance materials and purposeful design to solve the everyday frustrations presented by traditional underwear - they don't ride up and have mesh Breathe Zones for exceptional ventilation. Move through your day in the most comfortable underwear that was designed to move with you.

Our Athletic Fit Boxer Briefs fit true to size in the waist and have the same comfort enhancing features, performance fabric and waist size as our Standard Fit Boxer Briefs. The difference between the two product lines is the Athletic Fit features larger leg openings to accommodate guys with larger thighs - for instance, a medium size Athletic Fit boxer brief will fit guys with a 23" or more thigh circumference measuring 12" down from the waistline (the area where a waistband normally sits on your hips) - see our Fit Guide for the thigh circumference fit guide for all sizes.

    Great value

    Have held up very well after a year. Good performance for the price. Looking forward to trying the pouch design.

    They have been doing so good!! So comfortable! It’s cool to see that they still keep their shape after several washes lol

    Yeah i made a good decision to get the athelic one. It fits me really good! Price is acceptable! I’m waiting for the “paradise pocket” coming to see how it is.

    Finally, the perfect boxers!

    I have seriously tried a dozen brands of boxer briefs including both designer and expensive specialty brands like Tommy Johns. All Citizens are by for the best all around choice for literally less than half the price! The fabric & fit compare with the best of the rest. All Citizens also have the amazing horizontal fly and Paradise Pocket features making AC the best all around choice. Seriously, why would you buy any underwear with a horizontal fly? Its the only fly that makes any kind of sense and once you try them, you'll hate any other style. These are the first brand of boxer briefs I've tried with the Paradise Pouch feature and I'll never buy undies without this ever again. The pouch makes wearing briefs so much more comfortable and virtually eliminates embarrassing adjustments and other uncomfortable situations. No more "bat wings!" Please, please, please start selling the longer fit boxer briefs with the Paradise Pouch!

    Husband is happy

    My husband loves these boxers. He finally has a pair that fits his legs and that don't ride up because of the thicker band! Will definitely be getting him more.
