    I’m extremely picky about my t-shirts & underwear, especially because I wear an uncomfortable work uniform over 14hr shifts. These underwear are the most comfortable underwear in every way hands down. I’m surprised more companies haven’t copied the waist band. Oh, & my other half says she digs em the most???????? Now if they only made black t-shirts, because their white ones are amazing as well. -- RibbedTee Response -- Wowza, now that's one hellava review D-Gold! Thank you so much!

    Super comfy but really wish they had a fly

    Posted by Jon Proulx on 13th Oct 2020

    The are super comfy and they don't ride up. But I do wish they had a fly with my coffee habit it can be quite an annoyance. After a couple months of once a week wear the fabric did start to pill a bit on inner thighs, not too badly but something to be aware of. First impressions were amazing so as the secondary issues came up it was a bit disappointing they weren't the sublime perfection they seemed, but still would recommend just keep your expectations reasonable. -- RibbedTee Response -- Thank you Jon for sharing your feedback with us. We really do appreciate it, and will be sure to forward your comments and suggestion to our product team!
