FAQs ALPHX Modern Fit

What is ALPHX Modern Fit underwear?

Our Modern Fit underwear features a sleek, slim cut designed for men with slim to average-sized thighs. It sits just below the waist for a secure, stay-put fit, eliminating excess fabric for a smooth, tailored feel.

How does the Modern Fit differ from the Athletic Fit?

The Modern Fit is designed for a streamlined look with a slimmer cut, while the Athletic Fit offers extra legroom for those with more muscular thighs. If you need more space in the thigh area, our Athletic Fit may be a better option.

What styles are available in Modern Fit?

ALPHX Modern Fit is available in trunks, and boxer briefs, giving you multiple options to match your comfort and style preferences. We don’t offer an Athletic fit in our briefs because our hi cut leg opening already provides complete leg mobility.

How do I choose the right ALPHX fit?

If you have slim to average-sized thighs, Modern Fit is ideal for a sleek, tailored look. If you prefer extra room in the leg, check out our Athletic Fit for added comfort.
