"When I was first considering these I read a review from someone who said he was going to replace all of his old underwear with AIRKNITS. I thought it 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 much more comfortable than everything else."


"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 are wearing nothing."


“Apparently I have been living my life with the wrong underwear. The fit. The breath-ability. 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.”
