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. Move through your day in boxer briefs that were 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 fit and equally great customer service

    The fit on the Athletic boxer brief is exactly what I was hoping for. Not too loose, not too tight. I first ordered the standard fit but they were a little too snug around the thigh for my liking. Luckily the customer service here at All Citizens gave me a full refund and I was able to place an order for these athletic fit in no time!

    Great fit, comfortable material.

    Great value and comfort overall. The fly is a bit odd, but at least they have one. Love them.

    Fit well and don't ride up

    The fabric feels good and thigh fit is really good. I don't have to keep pulling them down my leg like I have to with other boxer briefs. Also very breathable.

    Most comfortable boxer briefs worn

    The elastic around the leg took some time to get used to, but these are the most comfortable briefs I've ever worn. Definitely think it's worth replacing all my other boxers in my wardrobe with.
