Love these running/non chafe undies. Highly recommended, nothing better. Thanks for a great product.

I brought these for my wife as I have been using the men’s ones for awhile, she was a bit sceptical about the sizing, I talked her into XL, she’s not an XL in size but they fit perfectly, she says they are very comfortable and do not move.


240kms of running through Aussie heat and mountain rain at Coast to Kosci and these held up brilliantly. I was blown away! Absolutely brilliant product.

More comfy than I thought. Excellent love it

I used it after recommandation of my husband who was using those shorts + underwear for some months, and I have to say that this is a great combo, light, doesn't keep the humidity, and perfect for races to carry the mandatory items. My go-to short anytime I need to carry water, phone and keys.
