    I bought several briefs and these were by far the best. They aren't the softest, but they don't ride up and most of the time I forget they are there, which is more than I can say for most. Also, next time I think I will order a size down as these are a bit large. -- RibbedTee Response -- Hey there Enoch -- good stuff there.Thanks for taking the time and sharing your positive feedback with us!

    Great underwear

    Posted by marc e. on 11th Jun 2020

    Cool, comfortable, this underwear is everything I need: a very small waistband that doesn't trouble my digestion. The only problem is the price (in US dollars, plus shipping, plus...), even if they are the best boxers I ever had. Also, this company should make the same garment with cotton (100%), so it would be cheaper, while producing the nylon ones for comfort. I think it's healthier to wear all cotton underwear, at least from time to time. Anyway, a very good buy! -- RibbedTee Response -- Great stuff there Marc! Thanks very much. We'll definitely share your feedback about making a 100% cotton boxer briefs as an option :)

    the best boxer briefs I have ever wore !! the only way to make them better is add a pouch and a functional fly and long leg that would make them the greatest . keep making them in U.S.A. -- RibbedTee Response -- Now that's music to our ears Smitty :) Ty!

    Very, very comfortable pair of underwear. Love the fact, This product is made in the USA. Most comfortable pair of underwear I’ve ever owned. And they don’t ride up my legs while working. I have a physically demanding job and you don’t want your boxer briefs creeping all day long. -- RibbedTee Response -- Love, love, love it! Thank you Joe :)

    Great quality, made in USA. Fast shipping, but minimum should be lower. -- RibbedTee Response -- Roger that Eric. We'll take that suggestion back to the team. Thanks so much for sharing your thoughts and review with us!
