    No chafing!

    I just started using the flex style which is little lighter than the first style I bought and have worked for years. The lighter material still fits perfectly and I use them full time on the motorcycle when temps start rising. My original woxers I use when it is cold. I don’t have any other underwear now. Just woxers.

    The fit is perfect and they don’t ride up.

    I am 5’10” and 210#. Thicc thighs and b*tt.

    I was so happy when i got them, but after 6 months of wear they have multiple holes on the crotch. I wash them cold with the delicates bag and air dry. The fabric is very very poor.
