Made from 94% sustainable materials: 56% cotton, 38% modal , 6% elastane.

Our Everyday Comfort Union Pant features our signature 120* Fly. Two dyed to match buttons are fastened at a 120 degree angle for ease of function and a modern aesthetic. This innovative design provides more room, making it easier to use, and secure when closed. Wear the Alphx Union Pant as a lightweight, breathable base layer for warmth without overheating, or lounge the day and night away in them. However you wear them, the 120* Fly detail creates a flattering profile and an updated look.

ALPHX is the first brand to offer a MDRN (Modern) Fit and an ATHLTC (Athletic) Fit in its trunks and boxer briefs. Our Modern Fit is great for men with slim to average thighs. Need more leg room? Our ATHLTC Fit gives you one additional inch of legroom in sizes S-XL. So now guys with thick or muscular thighs don't have to size up to fit their legs.

ALPHX Everyday Comfort Union Pant Layer or Lounge: your choice

What do you call a comfortable pair of pants you can wear as a base layer like long johns or hang out at home like lounge pants? Introducing the ALPHX Union Pant, made from the same soft premium fabric you have come to love in our underwear. Oh, we didn't skimp on any of the details, either.  

Underwear is your first layer, so comfort is non-negotiable. We use ethically sourced materials that are soft to the touch, beginning with lightweight, all-natural cotton for softness and breathability. We then add plant-based modal made from beech tree pulp for additional softness and an even more luxurious hand feel. (It doesn't sound like it, but believe us when we say modal is soft.) Finally, we add just the right amount of elastane for strength, stretch, and recovery.

We've got you covered, literally. Our ALPHX Union Pants have a modern rise, designed to sit below your natural waistline while providing full coverage in the back. We designed our signature 120-degree button-fly at an angle for easier use and a modern aesthetic.  Our Union Pants have a 30.5-inch inseam and a narrow 3.5-inch self-trimmed ankle stretch as you move, without stretching out or riding up.  

So layer-up or just hang out.  It's your choice.  We like choice.
