Daniel V.
Ran my first LA marathon in these. Design looked great, wicked away sweat very well, and best of all: no chafing!!
Andrew W
These are pretty amazing. I use mine for running, fast 5Ks and half marathons, and needed something for separation. Didn't even think about them during a recent race which is the whole point!
Ian
Easy ordering and quick delivery and most importantly very comfy for running.
Pete B.
Love the quality and the feel. Have tried them out running. PERFECTION!!
Pamela F.
My sons all love these boxers, great quallity and are good for larger thighs from rugby, running and body building!!
Graham A.
Great fit and so comfortable. I wear them while running and they don't chafe at all. I've tried other similar brands and these are definitely the best.
Chris B.
These boxers are the best around, I use mine when I'm powerlifting, running, walking etc.
Duane
Fantastic product, bought for long distance running to prevent chaffing. Would highly recommend
