Not Hassle Free, No Fuss

Do not buy. Not worth the price. Returns are not hassle free and are not No Fuss. You have to get approval, which takes days. You also have to pay for your own return. Any business that requires you to pay for your own returns and get approval is behind the times.

Thank you for your feedback, I am sorry to hear that you did not find the process hassle free and you had to wait for your approval email. I have passed your feedback onto the team and this will be reviewed.

Very comfortable, never reach for any adjustment. Is as if you're wearing nothing.
Love them.

Thank you for your feedback, Great to hear that you found your Runderwear Briefs comfortable and you feel as though you are not wearing anything. We love to hear this!

Men's Running Briefs (3 Pair Pack)

Thank you for your feedback, We hope you love your Runderwear purchases!

Good feel, but rides up

Underwear feels good and has great support, but my biggest issue is the ride up horribly. Walking 10 feet has them riding up and making me pick at them whenever I'm walking. During the run I can ignore it but once I stop it is wedgie central. I was really excited to try these but it kinda let me down. Overall I would say to buy them if you don't mind the wedgie and are looking for the straight support, otherwise if it is a long run I would say buy lined shorts.

Thank you for your feedback, I am sorry to hear that you are not getting along with the Runderwear Briefs. It sounds like the Boxers would be more suitable as they have the leg grippers to keep them in place and stop them from moving when exercising,

If you have any queries please do email where we will be happy to help.
