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

Both are 6-inch American Eagle boxer briefs with a contoured pouch and anti-roll waistband, so the split comes down to fabric and fly. The Flex pair uses a lightweight recycled-polyester blend with sweat-wicking and antimicrobial treatment, which suits workouts, hot days and travel. The Classic pair is a soft cotton blend with a functional fly, which suits everyday wear and anyone who wants a fly. Owners of AE cotton briefs tend to praise softness but report stretching and slower drying; the Flex fabric holds shape better and dries faster but feels more synthetic.

• Choose the Flex boxer briefs if you want sweat-wicking, odor-fighting fabric for the gym, travel or humid weather, and you don't need a fly.
• Choose the Classic boxer briefs if you want soft cotton against the skin, a functional fly and a more natural everyday feel.
