Dreaming of a better sleep without any leaks? This super-comfy sleep bottom with built-in coverage features leakproof technology that absorbs the equivalent of 12 tsp worth of liquid! A 10-14" gusset stops anything from leaking through. This underwear gives you full protection for periods, for a full night's sleep.

The gusset is our built-in pad that absorbs up to 12 tampons worth of liquid, and extends longer than our underwear styles at 27 - 35.4 cm (depending on size). It's quick-drying, and the top layer next to the skin is made with modal seaweed fabric.

Knix created Leakproof Underwear to be a sustainable alternative to your usual single-use pad and tampon monthly routine. With different absorbency levels that help reduce your period footprint, Leakproof Underwear are an eco-friendly and reusable replacement for disposable period products.

It's time that all of us lived unapologetically free. Free from judgment. Free from self-doubt. Free to be yourself. That's why all our products, from the most comfortable wireless bras to super absorbent underwear, are designed to make you feel more comfortable in your own skin. Using patented technology, cutting-edge processes, and human-centric design, we're creating products unlike anything you've ever worn. Whether it's lightweight anti-chafing shorts, wireless bras that are sexy and supportive, or overnight period protection, we want you to be able to find something that transforms how you feel.

At Knix, we aim to empower people and reduce environmental degradation by taking into consideration our impacts throughout production, transportation and consumption. Although we don't have all of the answers yet, we believe that making progress is better than waiting for perfection. We are transforming an underwear market that had too much frill and not enough function, so you can always feel your best at any stage of life.
