I was so surprised by our comfortable these are! It’s been so tricky to find knickers that actually sit right and are comfortable - there are spot on. The sizing is well done, and the quality is amazing. All round a great product!
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!
The Almond thong in an 8 is a great fit and true to size, really comfortable and lovely soft material . I’ve been looking for something like this for ages and I’m so glad I found it.
I’ve tried countless undies brands over the years, including some of the big names, and nothing comes close in terms of comfort, fit, and quality.
The organic cotton is lovely and soft without being flimsy, and the recycled elastic, (didn’t even know that was a thing) gives the right amount of support without cutting in.
I like that String Nix is built around everyday luxury essentials. It doesn’t feel like it’s trying too hard, it just is better.
No fast-fashion rubbish just beautifully made Nix and I’ve already recommended them to friends. I’ll be buying more, they are a game-changer.
I really like this product, they are extremely comfortable and don’t have any VPL at all. Can’t recommend enough, thank you.
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
Made with certified organic cotton which is super soft and extremely comfortable to wear.
They are easy to wash and I also put mine to dry in the tumble dryer on a gentle heat, even though it advises you not to tumble dryer them, they were fine, no shrinkage. Highly recommended.
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.
Great classy knickers, super comfy and top quality. Going to buy every color !
I love my Nix, the quality is amazing and so comfortable.
