Find Your Fit
All men are created equal, but our thighs aren't. So we're blowing up the industry size standards with ALPHX's exclusive leg width options. A first! Tired of your underwear riding up or pinching throughout the day? We hear you. Slimmer waist, bigger thighs? Bigger waist, smaller thighs? We got you. Choose your own unique combination of waist and thigh size and truly change your underwear game.
Our MDRN Fit sits just below your natural waist and has a slimmer contemporary leg fit. With 6% elastane for ease of movement, our MDRN Fit is perfect for guys who wear regular to slim-fit jeans. We added an additional half-inch to the diameter of our MDRN Fit to create our ATHLTC Fit.
It's great for guys who prefer athletic cut jeans with more room in the thigh or men who like their regular jeans a little looser in the leg. Available in our Trunk and Boxer Brief styles in sizes S to XL.
Because our briefs already have a high-cut leg opening, we only offer them in the MDRN FIT. Don't worry; we can add an ATHLTC Fit here, too, if needed.
Check out our size guide for actual measurements, or take our brief customized Size Finder to find your perfect fit.
As we get to know you better, we will expand our size offering.
