American Eagle AEO Flex Boxer Briefs vs American Eagle AEO 6" Classic Boxer Briefs

Both are 6-inch boxer briefs from American Eagle with a contoured pouch, anti-roll waistband and flat cover stitching. The Flex is the better pick for the gym, hot days and travel: its recycled polyester and elastane fabric wicks sweat, fights odor and dries fast. The Classic is the better pick for everyday comfort: its cotton-modal blend feels softer and breathes well, and it has a functional fly. Owners of the Flex line tend to praise the stretch and how well it holds up in the wash, while cotton-modal fans prefer the Classic for feel but note it stays damp longer after heavy sweat.

• Choose the AEO Eagle 6" Flex Boxer Briefs if you want sweat-wicking, odor-resistant underwear for workouts, humid weather or travel.
• Choose the AEO 6" Classic Boxer Briefs if you want a soft cotton-modal feel, a functional fly and everyday comfort.
