  • Ronnie
  • Men’s underwear

Very comfortable. Do not feel any straps binding me!
I wish You made these in a white color as well. ????

Hi Ronnie, thanks so much for the kind words about our G3 Men's Boxer Briefs! At this time we don't have any plans to offer them in white, but we'll be sure to share your color suggestion with our Production staff! Thank you once again!

  • OMH
  • Most Comfortable

First pair that I have tried, and so far, I love them. I especially enjoy the waistband. Since I am not the slimmest person , I have some underwear were the waistband rolls over, but not an issue with these. The fabric is most comfortable and lightweight. They are great for hot, humid, southern United States weather. I will certainly order another pair or two. Thanks for the great product.

Hey there OMH! Thanks so much for sharing your review of our G3 Boxer Briefs. So glad to hear you are staying cool & comfortable :)

  • Jacob
  • Better than the G2’s in every way.

The G3’s improved upon every aspect of the G2’s. Longer inseam, thicker fabric, more breathability, with the same tight conforming fit without getting irritating as most conventional cotton boxers do. Even the waistband feels more sturdy while somehow being a little looser simultaneously. Quite outstanding.

Great stuff there Jacob! Thank you so much for taking the time to review our G3 Boxer Briefs!

  • Dan
  • Just OK

These underwear are a little too heavy/thick for my taste. Plus the crouch pouch just doesn't work There's a reason no one else uses that design. I bought one pair to try them and will not purchase again.

-- RibbedTee Response --
Hi Dan, thanks so much for your feedback! We're sorry our G3 CoolNylon Boxer Briefs did not work out for you. We will be coming out with a TENCEL version of our G3 Boxer Briefs that will have a similar pouch construction, but they will fit a bit closer in that area due to the characteristics of the fabric. We hope you'll consider giving those a try when they come out later this year. If you'd like to be notified when they become available, please email us and we'll be happy to assist you further.

  • Daniel

  • Bob
  • RDR

I purchased three pair of your men’s underwear and was hoping the pouch would offer better support. I’m seeing more companies now offering men’s boxer underwear with a pouch sack to place your manhood in and also lifts them up away from the body holding everything inside the pouch. You ever get to the point of adding what they call a pouch sack I would definitely try your product again.

-- RibbedTee Response --
Thanks so much Bob! We're so happy you'd purchase our products again :) While our G3 Boxer Briefs for Men do not have a separated compartment for the family jewels at this time, it's definitely something on our product roadmap. We'll forward your feature request to our product team so they are aware of your preference to have a pouch with a separated compartment.
