  • Jay B.
  • Best Underwear Ever.

I'm very particular about my underwear-- I need a good amount of room in the pouch, material that doesn't ride, breathable fabric, ample support, and something that doesn't lose its shape after a wash. I'd found a pair or two that checked most boxes, but nothing that could do it all. Until I happened upon RibbedTee. I decided I wanted to support American-made businesses and found them through an internet search. This brand checks EVERY box I have, with the added bonus of feeling like I'm wearing nothing! I can't recommend these enough. If nothing else is certain, I know I will be a lifelong customer of RibbedTee.

Wow, thank you Jay for the INCREDIBLE review of our G3 boxer briefs!!! We're so happy you found us, and are enjoying your new American-made underwear ;)

  • Lee Gladin
  • Comfortable

I recently purchased some of the G3 Men's Boxer Brief to replace some old worn out pairs of old underwear I owned. The G3 Men's Boxer Brief are very comfortable. Ribbed Tee even took the important step to stitch them a certain way so as not to rub uncomfortably against your skin. So far I'm really pleased with my purchase of Ribbed Tee G3 boxer briefs. I've only had them a couple of months, so I cannot speak to the longevity. However, judging by the way they are made, I'm sure they will last me a very long time!

We're so happy to hear it Lee! Thanks very much for taking the time to review our G3 men's boxer briefs!

  • Moose
  • MADE IN U.S.A.

Buying American is the foundation to support the citizens of this great country. In my quest to find a quality pair has been challenging, however, persistence and patience has paid off. These underwear are everything they say it is and more. They feel great, support the family heritage and are worth every penny. I purchased 3 colors as a trial to see how they held up. I will be purchasing more and keeping America moving forward and supporting the hard working men and women of the U.S.A. Thank you.

  • Warren S.
  • Underwear Review

One of the most comfortable pair of underwear I’ve ever brought. Lightweight, breathable, and stylish. Wore a pair on a fishing trip and couldn’t be more happy.

-- RibbedTee Response --
Sweet! Love it! Thank you for taking the time to share your feedback and review with us Warren! So happy to hear you are happy with our G3 underwear!

  • Chris
  • Fantastic!

I looked all over for some boxer briefs made in USA. Finally found these, and they are great! Well-made, comfortable, and I reach for these every day.

-- RibbedTee Response --
We love hearing that Chris! Happy to hear you're enjoying your new G3 Boxer Briefs :) Thanks very much for your support, kind words, and of course your business.

  • John Couch
  • Best undies without a waistband

Pouch is comfortable. Lack of a waist band to roll or pinch is great!

-- RibbedTee Response --
Boom, now that's what we're talkin' about :) Thank you John!!

  • Rob
  • They shrink, be careful

G3 boxer briefs are really comfortable and I will continue buying them but be careful how you wash them and definitely don’t put them in the dryer because they will shrink bad. Started with mediums but my first two shrunk to unwearable size so I bought large and I’m Hang drying them.

-- RibbedTee Response --
Hi Rob, it is very strange to hear that you experienced any form of shrinkage with our G3 Boxer Briefs. Our underwear is pre-laundered, so it should not shrink, or shrink very little (1-2%), even if accidentally placed in a tumble dryer. We do recommend tumble dry low or lay flat to dry, which is the best way to care for your RibbedTee underwear.

If you'd like to send back the underwear for inspection, we'd be happy to replace your underwear free of charge. Please contact us at your first opportunity and we'd be happy to assist you further.

  • Joshua Munson
  • All day comfort

I ordered 5 pair of assorted colors of the men's underwear. These are the most comfortable underwear I have ever owned. I was especially glad to see that they are made in the USA. There is no slipping of the underwear up or down, and they offer support without being restrictive.

So happy to hear that Joshua!! Thanks so much for taking the time to share your feedback and review with us :)
