    Yep, they're underwear that you can use when you run. Or when you don't run. Either way, they're comfortable and do not chafe in the slightest. They're maybe a little more than I would want to spend on a single pair of underwear, but they do exactly what they're advertised to do. After washing them about 10 times, there is no deterioration in quality, so these appear to be very well made and fit true to size. Expect a snug but stretchy fit.

    They could have a better name.
    But they wear great. Have ran ultra in them without any problems. In Texas heat.
    Now own three pairs

    I've tried other brands of athletic underwear, but they all had seams and stitching in the most uncomfortable of places. Seriously, did they not try them on? But the Runderwear is by far the most comfortable of all. It took a little getting used to, but now I use them for everyday use. I would probably wear the mediums if I were using them for exercise but went with large for every day.

    Not for people with muscular legs

    Went running in them felt almost like I was naked. Only problem was my butt was too big and kept slipping out. Unfortunately I had to return them.

    Other then running a little large they are nice just wish the wrist band did not flop over all the time

    Comfortable and no chafing. I'll buy more.

    Great running underwear. They fit just right!

    Awesome for football.

    Fit is fine. Very comfortable for running.

    Ottimo prodotto

    Exactly what I was looking for
