I’m glad I waited a while to write a review. Upon first wearing them, I was pretty disappointed. The size small that I ordered seemed too big. I couldn’t believe they were the smallest size. But after wearing a couple times, I grew to absolutely love them. They didn’t lose their shape by the end of the day the way some can, and are incredibly soft and comfortable. Now I can’t believe I was wearing such tight undies for so long. I had no idea what I was missing.

A bit less fabric than expected. Would prefer someone of a rugby build as well in photos as those of us with bigger thighs need a better representation.

Softest most comfortable underwear. My wife is conscious of the materials we wear. Will definitely be getting more Stone.kin and I imagine these will be the only brand we wear

I now nearly have a pair for each day of the week - that's the goal: every colour combination there is. But the next step is to buy my woman a voucher ❤️

My wife put me on to these guys and finally a male underwear manufacturer that provides a soft stretch waist band that doesn't squeeze your stomach like an elastic band!!!
It's good to see someone is prepared to actually use the correct stretch materials instead of the cheap nasty ones used by the likes of Bonds.
As for fit, comfort and style, all excellent.
Highly recommended!

Hello, I bought 6 pairs of these paints within this order and a further order in Nov 2025. Of the 6 pairs, 3 have torn where the waste band is stitched together on the side - see photos attached of two of the pairs. Messaged Stone Kin for comments but have not heard back. Colours are great but cannot recommend as the quality is really disappointing. I would expect that I am not the only person that has had this issue.

Hi Robert,

We’re so sorry for the disappointment and appreciate you bringing this to our attention. We responded to you promptly and have been in touch privately to resolve the issue. We’ve also issued a refund for the three faulty items.

Kind regards,
