Paul White said: New runing kit needed

I am informed that the fit is perfect. As a result this generous gift from her "outlaws" she is back in training. It was the inspiration she needed.

Jean Roffe said: Fab running undies ‍♀️

Very comfy great fit well worth the money I would definitely recommend then to my running friends

Bob Frake said: Mens Runderwear White Boxers

Really comfortable on a long run. So they are recommended.
However I should've gone for black though
When you've been on a muddy run, it gets all over them when you take them off.
GO FOR BLACK

Bob Frake said: Mens Runderwear Cricket Briefs

Not a keen fan of briefs but thought I'd give them a try. Comfortable enough on a 10k run, but I kept thinking my nads were hanging out the sides, so I prefer the Boxers

Ian said: Work Perfectly

No chafing, rubbing or “popping out”. Highly recommended for running.
