    Comfortable but overall quality?

    Posted by Carlos on 16th Nov 2019

    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 -- Hi Carlos, Thank you so much for your order and for taking the time to provide your feedback.

    Great comfort

    Posted by John on 6th Nov 2019

    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. -- RibbedTee Response -- Hi John, Thank you for your purchase, your support, and for taking the time to provide your feedback! We're so happy to hear you're enjoying your new RibbedTee CoolNylon underwear. Seems as though you've received an item with a defect or irregularity, and we're terribly sorry that has happened.

    Great comfort and excellent quality

    Posted by Sunny on 17th Oct 2019

    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. -- RibbedTee Response -- Thank you so much Sunny! We certainly do appreciate it :)

    G3 Men's Boxer Brief | CoolNylon | Light Grey

    Posted by Gerard on 9th Oct 2019

    I bought 1 pair of underwear and 2 tee shirts. I am very happy with the material in the items but... I’m from Ireland. I bought the products knowing that you would charge extra for the shipping, but because you advertise the products and the price on the outside of the package my country decided to charge me for customs and extra charge for delivery (over 32.00 dollars) so in total I paid 150.59 for the 3 items. So I can not order again, and also I would have liked more privacy on the label. I did like the products though. -- RibbedTee Response -- Hi Gerard, Thank you so much for your recent order and for taking the time to share your feedback with us! We are very happy to hear you are enjoying your new RibbedTee gear! Regarding the extra charges related to delivery/customs -- we do apologize, but USPS & Postal Union policy requires the inclusion of Customs information on the shipping label. If we were able to bypass that requirement for our international customers, we surely would :) One possible work-around would be to take advantage of our 20% off offer for orders $200+, allowing you to offset any surcharge fees placed on your shipment by your country. Thank you once again!

    Underwear, Briefs

    Posted by Sandy Poffenberger on 4th Oct 2019

    I bought one of these to see if my husband liked them. We try to always buy USA made. I ended up getting him one for everyday of the week. They are great quality and it's almost like your not wearing anything. Highly recommend! -- RibbedTee Response -- Thank you so much! So happy your hubby is enjoying his new USA-made underwear :)

    These surprised me...

    Posted by The best-all-around 6” Boxer Briefs. on 21st Sep 2019

    I’ve tried everything from MeUndies, Mack Weldon, 2Under, Jockey etc...these so far these are the best all-around 6” boxer briefs. They are the best combination of soft, durability and breath ability. For having big quads, these did not move up at all. I personally have one brand for sleeping(at home) and one for work/travel, but if you’re looking for an everything 6” boxer brief, these are are them. I only took 1 star off bc I’d prefer them with a fly/8” inseam. Keep up the good work guys. -- RibbedTee Response -- Thanks so much! We're happy to be your Everything 6" Boxer Brief of choice :)
