  • David Geveke
  • Great Underwear

These are super supportive and comfortable. I’ve worn and washed them about five times already and they are as great as when they were new. And, they’re made in the USA. I’m planning to order three more.

  • Kevin
  • Very Satisfied with my purchase

I had two goals: Buy underwear that held things in place. Buy underwear made in the USA. If you are willing to purchase underwear NOT made in the USA then this review may not be as helpful. I spent about an hour searching for the style of underwear I wanted that was made in USA. There are not a lot of choices for top line products made in the USA. I purchased one pair of ribbedtee and one pair from a competitor. Both pairs fit and felt great, but when I started working on an excavation project that took a few days I found out which brand to buy. With the ribbedtee product things stayed nicely inside the underwear no matter how hard I worked. The next day wearing the competitor's pair I was unhappy to have to stop work, reach down inside and put things back into place. The next day I ordered three more pairs of ribbedtee. The other pair from the competitor I only wear when I'm not going to be active.

  • Enoch
  • Great

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.

Hey there Enoch -- good stuff there.Thanks for taking the time and sharing your positive feedback with us!

  • Jeremy Soza
  • Really like them except... significant pilling

I like everything about these, my only issue is that my little over than a week old pair has significant pilling on the seat of the boxer briefs. I've hand washed them once and tonight I ran them in my washing machine on delicate and let them hang dry. I only noticed the pilling tonight but I'm not sure as to what is the cause. My only guess is that I wear a lot of nylon and other synthetic fiber fabric pants- maybe they are what is causing the abrasion to the seat of these that is leading to the pilling? I'd like to buy more, but only if I can figure out a way to prevent the pilling. I think hand washing is my only option for this pair though.

-- RibbedTee Response --
Hey Jeremy, thanks for stopping by and sharing your feedback. It's quite strange to hear that the seat of the boxer briefs are pilling so quickly. It is possible there is some fabric abrasion going on between your pants, but it does seem strange still.

Pilling can be cleaned from fabric either using a de-piller, or using a face razor (just pull the fabric tight, and gently slide the razor over the fabric). If you'd like, please contact us and we'd be happy to assist you with a return-for-inspection, and free replacement. We look forward to hearing back from you.

  • Great underwear

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 :)

  • Michael

  • smitty
  • made in the U.S.A. like it should be please never change that

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.

  • Joe Gerstner
  • Sweet, sweet Support

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.

Love, love, love it! Thank you Joe :)
