The Hi Brief in Organic Cotton Rib – Tar is designed for grounding comfort and timeless simplicity. Made from GOTS-certified organic cotton rib, it feels naturally soft, breathable, and smooth against your skin. A hint of elastane adds gentle stretch, giving you flexibility and lasting shape through every wear.

This Hi Brief in Organic Cotton Rib features a high-waisted silhouette that flatters and supports, refined with a cotton waistband in matching Tar and the minimal stone.kin logo. The deep, earthy tone captures quiet strength and ease a reminder that comfort can be both subtle and empowering.

Every Hi Brief in Organic Cotton Rib – Tar is consciously crafted: non-toxic, plastic-free, and made to last. It’s underwear that reflects the essence of Stone.kin natural, honest, and deeply comfortable.

Looked so old in shape at first but when you put it on it is so comfy! the Band is also snug and not tightening, I will buy again.

Was given a stone kin gift card for my birthday earlier in the year & these undies are the most incredibly comfortable things ever! Love everything I purchased but these are the selection favorites!

Nice material and colour but the waistband I find a bit tight for my liking, and I did size up as well.

Gorgeous pieces! It did take me a day or two to get used to the fit, but I'm now totally in love. Can't wait for the matching bra to come back in stock!

these undies continue to be my favourite ones, the fabric is super comfy and they mold your butt well, they do not flatten it, and also the waist elastic band lasts forever, and doesn't push your belly, not make you feel uncomfortable. if using pads, the wide down there helps it stick well and stays well too...
nothing bad to say, just hoping I can buy the most popular colours when they are back in stock

as always, the quality and comfort of the fabric is amazing, these are my favourite undies. The new colours are lovely but I couldn't buy the more popular ones because of sold out. I had the first first colours so I wanted to obviously keep buying this brand next ones.
I do think the previous elastic band colour which was grey with the brand name in black was more appealing and had a more serious cool and interesting look, it contrasted much better with different colours. For me at least it was more calling.... hihihi

Anyways, keep on producing them. they last long and the fabric is super comfy and doesn't flatten your butt, it makes it look nice!

I bought these and the cheeky in a M - the cheeky cut fits perfectly but I found the full brief seemed to have a bigger fit.

I’m always hesitant about buying things online, but I’ve never regretted this purchase! These undies are sooo comfortable and soft. I can’t wait to buy more of them in different colours.
