ALPHX Athletic Fit Boxer Briefs – Maritime Navy

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.

Color Story

Maritime Navy

Maritime Navy is a deep, ocean-toned blue that feels classic but modern — softer than black, richer than standard navy.

It delivers contrast without sharpness, making it an easy everyday alternative that still reads polished and refined.

A natural choice when you want color that feels elevated, not seasonal.
