We thought the classic brief deserved an upgrade. We built ours from the ground up, starting with our super soft 18-hour Jersey and adding design features like a no-roll waistband and mesh cooling zones for optimal comfort. It’s a classic brief. Only better.


From the fabrics that we create, down to the stitches and seams, we've focused on the details so you don't have to.

"Turns out those boxer-briefs are hands down the most comfortable and best fitting underwear I’ve ever worn. Not kidding!”- Matt, VA
”The material is super nice and the fit is great, I look pretty amazing in them or at least “that’s what she said.””- Matt, CA
”Your underwear fits me “right outta da box!” Not too snug - yet supportive. Not too loose - yet not baggy/saggy. And so soft!”- John, LA
”Mack Weldon underwear is legit, by far the best I have worn. Comfort level falls somewhere in between not feeling like I am wearing underwear while not going full-commando status. Sheer perfection. You messaging me is the cherry on top and I will definitely be shopping here in the future.”- Derik, AZ
