The brief has come a long way from the "tighty-whities" Mom bought for us as kids. The truth is they look good on everyone. Sometimes Mom did know best.
We've got you covered, literally. Our ALPHX Briefs sit just below your natural waistline while providing full coverage in the back. We engineered a double-lined, contoured pouch that's deep where you need it and streamlined where you don't for maximum comfort and support. And the high-cut leg opening gives you complete leg mobility and an attractive profile.
Underwear is your first layer, so comfort is non-negotiable. We start with materials that are soft to the touch: lightweight, breathable natural cotton, and modal made from beech tree bark pulp. (It doesn't sound soft, but believe us when we say it is.) Next, we add just the right amount of elastane for strength, stretch, and recovery. Finally, our waistband is obnoxious-free. It's dyed to match the underwear creating a slimmer appearance, and is subtly embossed with our signature ALPHX logo.
Comfortable, Slimming, Attractive, Subtle: Alphx Briefs.
Our MDRN FIT is designed to sit just below your natural waistline. Our brief is slim through the back while still providing full coverage: no droopy drawers. We promise. 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.
How you like your underwear to fit is personal. ALPHX offers 130 style, size, and color options to choose from, so we encourage you to use our customized Fit Finder to help you identify the size and fit that's right for you.
Our briefs are available in sizes XS through XXL. The numeric equivalent is 26"-46". See our size guide for details.
By the way, FREE SHIPPING IN THE USA! We like free. Competitive rates internationally.

The fit and fabric of the Brief is top notch. Kept everything in place without feeling restrictive and love the detail in design. I’ll definitely be adding Alphx to my collection!
I ordered the brief in a different color and size the first time and I love them both. My next order wiki com tomorrow as soon as I have a free moment.
The best most comfortable pair of underwear! ❤️
These briefs make me feel sexy LOL and are so comfortable.
