ALPHX Boxer Briefs Athletic Fit Glacier Blue- Extra Room

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.

“Finally boxer briefs that don’t squeeze my thighs.”

Color Story

Glacier Blue is a cool, ice-toned blue that reads like a modern neutral — crisp, minimal, and easy to style.

It’s the clean base layer shade in the Athletic Fit lineup: subtle under light trousers, polished under dark, and always refined.

A go-to when you want fresh color without loud contrast.
