Join ALPHXTRAS

The ALPHX trunk gives you all the support of briefs plus additional leg coverage. 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, our simple turn-back leg stays put with no awkward visible binding line under your trousers.  

For those of you who find wearing trunks uncomfortable, we got you. Our exclusive modern and athletic cuts eliminate painful pinching and annoying ride-up by allowing you to combine your preferred leg fit and waist size.  

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. 

Bonus fact: Trunks also make your legs look longer, meaning you appear taller. I mean, come on!

Comfortable, Slimming, Attractive, Subtle: Alphx Trunks.


       

       

       

      Be Comfortable

      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.  Try a pair risk free with our Be Assured Guarantee.

      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, for strength, stretch, and recovery, we combine these two materials with just the right amount of elastane. Our tonal waistband is obnoxious free subtly embossed with our signature ALPHX logo.

          MDRN FIT

          Our MDRN Fit sits on your hipbone, just below your natural waist, and has a slimmer contemporary leg fit. With 6% elastane for ease of movement and our stay-put leg construction, the ALPHX MDRN Fit stretches with you as you move without stretching out or riding up. Our MDRN Fit is perfect for guys who wear regular to slim/skinny-fit jeans.

          ATHLTC FIT

          Looking for more leg room? We added one additional inch in leg circumference to the MDRN Fit to create our ATHLTC Fit, making it an excellent option for guys with thicker thighs or large/muscular legs. In addition, our ATHLTC Fit is perfect for guys who wear athletic-fit jeans or prefer a looser leg fit in their underwear. Oh, and unlike the airlines, we don't charge more for additional leg room. Medium waist and muscular thighs? Choose Medium ATHLTC. Large waist and average to thinner legs? Choose a Large MDRN. Try our easy-to-use Fit Finder to help you determine which combination is right for you. As we get to know you better, we will expand our size offering.

          Available in our Trunk and Boxer Brief styles in sizes S to XL.
