ALPHX Boxer Briefs Modern Fit | Midnight Black

Q: How does Athletic Fit differ from Modern Fit?

Athletic Fit offers extra room through the seat and thighs while maintaining a secure, supportive waist. It’s designed to prevent leg squeeze, ride-up, and restriction without feeling loose or oversized. Modern Fit features a more tailored leg opening for a streamlined, close-cut silhouette.
