Why you’ll love it

Designed for muscular thighs. Built with a cleaner leg line.

  • Athletic Fit construction — engineered with extra room through the seat and thighs to prevent squeeze, restriction, and ride-up.

  • Shorter 2” inseam — delivers a streamlined, modern silhouette without sacrificing coverage or comfort.

  • Premium cotton-modal blend — ultra-soft, breathable fabric made from 56% cotton, 38% modal, and 6% elastane for natural stretch and all-day wear.

  • Engineered support — a contoured pouch provides secure, natural support without compression.

  • No ride-up design — balanced rise and leg openings stay in place during movement, workouts, and long days on your feet.

  • Thoughtfully made — crafted from 94% plant-based fibers and shipped in biodegradable packaging with carbon-offset checkout via EcoCart.

“Finally, trunks that fit my legs without feeling tight or restrictive.”

Color Story

Midnight Black is a true, inky black with depth — clean, sharp, and endlessly versatile.
It’s the most essential color in the Athletic Fit lineup: invisible under dark layers, grounding under light ones, and always intentional.
The default when you want zero distraction and maximum confidence.

FAQs

What are your product sizing details?

Our boxer briefs fit true to size at the waist, with a modern, close-to-the-body feel similar to most men’s pants today.

ALPHX offers two leg fits per waist size:

  • Modern Fit — Ideal if you wear regular or slim-fit jeans
  • Athletic Fit — Designed for muscular thighs or anyone who prefers more room through the leg

Use our size chart or Fit Finder to find your best fit.

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.
