    Best underwear. Awesome material that supports yet gives for free movement. The waist band is the only thing I’m not a massive fan of but it doesn’t necessarily bother me. -- RibbedTee Response -- Thank you Grant!

    Well worth the comfort

    Posted by Francisco on 11th Apr 2020

    I was in the market for underwear that would provide comfort during a workout and at the office. These did not disappoint. The nylon and spandex combo make for a cool wear and the best part is the elastic allows for unrestricted movements. I will order more in the future -- RibbedTee Response -- Hi Francisco, thank you so much for taking the time to provide your feedback. So happy to hear you're enjoying your new G3 CoolNylon boxer briefs!

    New favourite

    Posted by Cameron on 18th Dec 2019

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

    Best briefs by far

    Posted by John on 12th Dec 2019

    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. -- RibbedTee Response -- Thank you John!

    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!
