  • “Apparently I have been living my life with the wrong underwear. The fit. The breathability. The POUCH. I mean…I’m cool, comfortable, and now supported by more than my overbearing mother. I’m happy to start my new life with Mack Weldon.”

    -Ben

  • “When I was first considering these I read a review from someone who said he was going to replace all his old underwear with AIRKNITS. I thought this was a little bit ridiculous. Now I think I will eventually do the same over time. I would wear these every day if I had enough of them. They are that much more comfortable than everything else.” 

    -Ron

  • “My husband will only wear these boxers. He says they keep him from not sweating and the wicking is the best and feels like you’re wearing nothing.”

    -Dodie
