American Eagle AEO 6" Ultra Soft Boxer Briefs vs American Eagle AEO Flex Boxer Briefs

Both are American Eagle 6" boxer briefs with a no-fly contoured pouch and anti-roll waistband, so the choice comes down to fabric. The Ultra Soft is a modal-rich viscose blend that feels plush and drapes softly, which suits lounging and everyday wear. The Flex is a lightweight recycled polyester performance fabric with sweat wicking, antimicrobial odor control and flat cover stitching, which suits the gym, hot days and wearing under denim. Owners of modal blends generally report the softest hand feel but more pilling and stretch loss over time; polyester performance knits hold shape and dry faster but feel less luxurious.

• Choose the Ultra Soft if you want the softest, most comfortable fabric for lounging and everyday wear.
• Choose the Flex if you sweat, work out, or want odor control and a smooth line under jeans.
