American Eagle 6" Flex Boxer Briefs vs American Eagle Classic Boxer Brief 3-Pack

Buy the 6" Flex 5-pack for workouts, hot days and travel: the recycled polyester-spandex blend wicks sweat, fights odor and dries fast, and the longer inseam stays put under shorts. Buy the 4.5" Classic 3-pack for everyday wear if you prefer cotton against the skin and want a functional fly. Both share the brushed anti-roll waistband, contoured pouch and flat stitching, so the real split is fabric and fly, not build. Owners of the Flex line praise the softness and hold but note the no-fly design; cotton fans find the Classic breathable but slower to dry.

• Choose the AEO 6" Flex Boxer Briefs if you sweat, train, or want odor control and quick drying in a longer 6" leg.
• Choose the AEO 4.5" Classic Boxer Briefs if you want soft cotton, a working button fly, and a shorter leg for daily wear.
