Wow! Our sales have outpaced our expectations, and we have already sold out of some items. But, no worries, we have more on the way and expect to be back in stock by the end of December. So, place your backorder today to reserve your quantities.
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. Full support, complete leg mobility, and did we mention sexy? Ours are. Sometimes Mom did know best.
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.

Our Underwear is understated, but never basic. ALPHX is designed for everyday comfort and we think, stylish enough for special occasions too. You be the judge.

We start with materials that are soft to the touch: lightweight, breathable natural cotton, and modal made from beech tree bark pulp. (Doesn't sound soft, but believe us when we say it is.) Then, we combine these two materials with just the right amount of elastane for strength, stretch, and recovery. Finally, our waistband is obnoxious-free. It's died to match the underwear and subtly embossed with our signature ALPHX logo.

Awesome fit, feel and support. Excellent customer service too!
The quality is amazing. The fabric is thicker and softer than similar brands. The waste band is also wider. They fit great. These will last a long time.
As a personal trainer, strength coach, and professional powerlifter, I find myself running through underwear all the time. I finally found a couple pairs that are comfortable enough to wear anywhere, anytime, but also ones that perform really well in the gym. I require a good amount of support and something that’ll fit my big butt and legs. The briefs (and trunks) are supportive and moisture wicking like good compression underwear but are soft and comfortable to wear for literally anything. Other pairs of underwear that I’ve tried with modal fabric blends are usually too flimsy and sweaty for me so these are a holy grail find!! I prefer a rather snug fit so i went with the medium modern in both the briefs and trunks (I'm 5'10", 190lbs). Bonus: my girlfriend appreciates how they make my butt look, and I agree!! Fabulous product, fantastic mission, I’m very happy with the purchase!!!
I cannot tell you how happily surprised I was when I received my MDRN fir briefs. I was in search of something both well made, as well as more muted/sophisticated colours and these hit the mark!! The fit is phenomenal offering both support for sport and full coverage (even for my more than "ample-thanks-to-squatting") booty and the colors are rich with a subtle sheen that elevates the entire look. I can't wait to get my hands on more and see the next group of colorations. I'm hoping for a chocolate brown!
Now, stop reading and GO BUY SOME ALPHX!!!!!
I was a little suspicious when yet another line of underwear was in the market. But I was more than pleasantly surprised when I got the underwear and saw and felt the fit! Very nice ! Thank you
