    “I've experimented with a lot of running underwear over the years and T8 undies are top notch. Super lightweight. Feels like wrapping balls in cotton wool and beats lube hands down.”

    “T8s are the first pair of specific running underwear I have owned, and boy was I impressed. They are so lightweight and comfy, they have even snuck into my regular non-running undie rotation.”

    “Fantastic breathable running underwear for high intensity and ultra trail events. They are feather light with size small coming in at a mere 36g. Keeps your junk in place and chafe free!”

    “T8 underwear is the goods. Did a 47km tester under the boardies and managed to dive straight into the salty ocean post run (still in jocks and boardies) and no chafe sting so a true test!”

    “It was a happy beginning, middIe and especially ending and I even dispensed with my usual liberal application of lube. I would be happy to have a couple of these bad boys in my closet”

    “Over the years, I have suffered some pretty horrendous chafe. I wore the T8 running underwear for 320km across Cambodia and liked them so much that I wore them everyday and didn’t get any chafing.”
