Find Your Fit

Find Your Fit

ALPHX was created to help men fit better, feel better, and be better.

We understand that the perfect fit makes all the difference, especially when it comes to your underwear. That's why we've engineered two unique fits - The ALPHX MDRN Fit, and ALPHX ATHLTC Fit - to cater to varying preferences and body types.

MDRN Fit:

Our MDRN fit is designed to sit just below your natural waistline, offering a contemporary, slimmer leg fit. Crafted with 6% elastane, this fit ensures ease of movement, making it ideal for individuals who prefer regular to slim-fit jeans. It's a versatile choice that strikes the perfect balance between style and comfort.

ATHLTC Fit:

For those seeking a little more room in the thigh area or a slightly looser leg fit, our ATHLTC fit is the answer. We've expanded the leg circumference by an inch from our MDRN fit, making it perfect for guys who typically opt for athletic-cut jeans or prefer a more relaxed feel in their regular fit jeans. If you’ve ever had to size up in the waist to fit your legs, you will love the ALPHX ATHLTC Fit. A boxer brief in a size medium ATHLTC fit is the equivalent of a size medium waist with a size large leg opening.  

Available Styles and Sizes:

Our MDRN Fit is available in all of our styles in size XS-XXL.  Our ATHLTC fit is available in all of our styles except our briefs (Our high cut leg opening works on slim and large thighs) in sizes S to XL.

Customized Fit Finder:

Understanding that underwear fit can be subjective, we encourage you to explore our customized fit finder tool. Whether you're searching for the best underwear for athletic men, seeking comfortable options for larger legs, looking for something sexy, or aiming to find the best boxer briefs for men, our fit finder employs both measurements and fit preferences to guide you toward your perfect fit.
