The ALPHX boxer brief gives you all the support of briefs plus additional leg coverage without the extra fabric and bunching of conventional boxer shorts.
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. With a 4.5-inch inseam our boxer brief prevents chafing and is still short enough to wear under most shorts. And, our simple turn-back leg stays put with no awkward visible binding line under your trousers.
With our exclusive modern and athletic cuts, ALPHX eliminates 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 is dyed to match the underwear creating a slimmer appearance, and is subtly embossed with our signature ALPHX logo.
Be comfortable in your own skin. Be Alphx.
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.
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.

Fantastic and what I was hoping for! Didn’t even have to pay duty on them coming to Canada :)
Purchased several pairs for my husband and completely thrilled. He just adores them! These are the best boxer briefs he has ever owned. Love the quality and feel of underwear. I especially love the body positivity message and support of mental health. Thank you Alphx!
Amazing stretch and fit.
Really like these but can you consider adding a fly to a pair down the road? Call me old fashioned.
I appreciate the wider leg width because I like underwear that’s loose around the leg. Really comfortable
