The Thong in Organic Cotton Rib – Lake is where softness meets style. Designed with a sporty low line thong cut, it sits lightly on the body and flexible, breathable, and made to move with you. Crafted from GOTS-certified organic cotton rib, it feels gentle on the skin, with a hint of elastane for subtle stretch and lasting shape.

A thin gel leg liner helps minimise visible panty lines, keeping the look smooth under clothing without sacrificing comfort. The rich cotton waistband, finished with a minimal stone.kin logo, brings a quiet refinement to the silhouette understated, thoughtful, and grounded. The Lake tone is deep and cooling, inspired by still water and calm mornings.

Every Thong in Organic Cotton Rib – Lake is made from non-toxic, plastic-free materials, staying true to Stone.kin’s commitment to comfort that honours the body and the planet. Softness you can feel. Simplicity you can trust.

At Stone.kin, we believe in underwear that supports your everyday rituals gentle, mindful, and beautifully made to last.

So in love with this top- I am actually going to wear it as a bikini on the beach. The softest highest quality material and the cutest design!

Beautiful colour, very comfy. I did get a crop to layer under it, I would love to wear it without anything underneath but it is a little low and thin. Would be great if there was a double layered one. Still love it though

Feels like I'm not even wearing anything - love love love, I got a range of items and these are probably my favourite, have been wanting new cotton gs for so long and haven't been able to find any that I really like. These are going to end up replacing all my old ones.

Love it! Read so many positive reviews and had friends recommend Stonekin and they were all correct - so soft, so comfortable often like wearing nothing. I am usually a size 8 with small B cup, and got everything in a medium and am very happy with the fit and coverage.

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

I love this so much! Was unsure if bikini style would be odd as underwear but it is so soft and comfy, I love that I can wear it under open tops or even by itself as a top. Colour is as pictured (I got the papaya)

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!

Excellent fitting bra and very comfortable. I bought a size small and it was a perfect fit. Fabric is very soft too. I would love one these with a bra clip instead of having to put it over your head. Highly recommend this bra - I'll be back for more.

Fave undies, price of mind knowing I’m not wearing plastic, toxic dyes. My whole family wear stone kind and love them

I bought it to wear in the sauna and cold dip to reduce microplastics. It's a lovely colour and feels so soft. First use in the sauna went well.

I’ve been waiting for this color in the bodysuit and so thrilled it’s out! Such a gorgeous color next to a summer tan :-)

I used to wear anything. Now I choose organic for the parts of me that need it most. For my hormones, my skin, and my peace of mind.

Amazing fabric, feels so good to wear and the colours are vibrant. A nice change to have options in clean undies. Will definitely buy more. True to size.

I absolutely love these underwear; they are the most comfortable and well made thongs I have come across. Hoping more colors are restocked soon!!

Amazing bodysuit! I'm glad I messaged the team to check what size would fit me. My bra size is 33A, Hips 38, Waist 28 in and the size M sits perfectly. Many compliments already received. Will purchase more of these in different colours.
