  • Cameron
  • New favourite

I've worn them to work and when out running and they are very comfortable and supportive. You don't notice them, they just do their job. Not owned them long, but if they prove durable I'll be very happy.

We couldn't have said it better ourselves Cameron :) We hope you continue to enjoy your new RibbedTee G3 boxer briefs!

  • John
  • Best briefs by far

These are without a doubt the best briefs I have ever worn. Lightweight, smooth, with great stretch. When a previously purchased pair had a manufacturing flaw, RibbedTee replaced the pair quickly. I compliment them on a great design, ethical service and standing by their products.

Thank you John!

  • K Greene
  • Wow!

I had read other reviews and even watched a youtube video reviewing the ribbedtee products. After the reviews I had to try them for myself and all I can say is WOW! I wish I had found these long before now. As I am writing this review, I am anxiously awaiting my second order to be delivered.

-- RibbedTee Response --
Good stuff there K :) We couldn't be more thrilled to hear that our boxer briefs WOW you!

  • Ramon
  • Best Underwear I have

I will admit that this is the most expensive boxers I have ever purchased, but so far it has been definitely worth it.

  • Carlos
  • Comfortable but overall quality?

First time wearer and overall I am impressed. They are comfortable and rise up minimally but I have yet to wash them and I am currently wearing them, so technically worn once and one of the leg 3" leg stitching pulled out on its own, a bit disappointed by that, hoping it is just a defect.

-- RibbedTee Response --

  • Great comfort

Awesome comfort, lightweight and material is breathable. These are best briefs I've owned. Bought 4 and will order more. One pair had 3" of waistband stitching pull out of material after 2 wearings and 2 washings.

  • Sunny
  • Great comfort and excellent quality

I appreciate the great comfort and quality of materials, probably one of the best in the market, lot of products are overpriced with brand name, this is still expensive, comparative to other products worth the price. I ordered over 5 colors, I will order in future, and I will recommend this product to my friends.

Thank you so much Sunny! We certainly do appreciate it :)
