FAQs ALPHX Athletic Fit

What is ALPHX Athletic Fit underwear?

Our Athletic Fit underwear is designed for men with larger or muscular thighs, providing extra legroom while maintaining a secure, stay-put fit. It eliminates pinching, riding up, and restriction for all-day comfort and mobility.

How does the Athletic Fit differ from the Modern Fit?

The Athletic Fit offers an additional 1.6 inches in thigh room for a relaxed, non-restrictive feel, while the Modern Fit has a sleek, slim cut for men with slim to average-sized thighs. Our Athletic Fit provides an extra 1.6 inches in thigh circumference per waist size compared to our Modern Fit—essentially giving your legs the fit of one size up. For example, a Medium Athletic Fit has the same waist size as a Medium but the thigh fit of a Large Modern Fit.

What styles are available in Athletic Fit?

ALPHX Athletic Fit underwear is available in our trunks and boxer briefs, offering the perfect balance of support, flexibility, and breathability. We don’t offer an Athletic fit in our briefs because our hi cut leg opening already provides complete leg mobility.

How do I know if Athletic Fit is right for me?

If you have muscular thighs or prefer extra room, the Athletic Fit is perfect for a relaxed, non-restrictive feel. If you like a closer, more tailored cut, try our Modern Fit instead.
