A new level of comfort

I’ve got two pairs in different colours - these are the best knickers I’ve got by a long shot. They’re so comfortable, the size fits perfectly and you can feel the fabric quality. I will definitely get more!

Super, luxurious and comfortable!!

Cannot recommend enough! They wash extremely well, keep their shape and I’m loving them, they are great under fitted trousers/skirts with their seamless look and are super soft

Comfortable and Eco friendly

I was hesitant to try a new brand of string thong after years of searching for the perfect one, but Stringnix changed my mind. Made from organic cotton and recycled materials, it’s both eco-friendly and incredibly comfortable. It’s also ideal for Pilates and running, offering a seamless, no-VPL fit. I’d recommend sizing down, as the fit is quite generous, especially at the front.
