Knix designs comfortable wireless bras and leakproof seamless underwear.

Knix is an underwear and activewear brand that is committed to empowering individuals by providing innovative and comfortable products that support and enhance its customers everyday lives. 

Knix was founded in 2013 by Joanna Griffiths, a young entrepreneur who was frustrated with the lack of functional and comfortable underwear options for women.

Inspired by her own experiences and the stories of countless other women, Joanna set out to create a brand that would revolutionize the lingerie industry. She wanted to create products that were both functional and fashionable, and that would help women feel confident and comfortable in their own skin.

Knix's mission is to empower individuals by providing them with products that address their everyday needs and challenges. Whether it's through leakproof period underwear, wireless bras, or activewear, Knix is dedicated to creating innovative solutions that make its customers lives easier and more comfortable.

What makes us unique is our commitment to inclusivity and diversity. We offer a wide range of sizes, from XS to 4X, and are constantly working to expand size ranges and offer products that are inclusive of all body types. Additionally, we're committed to using sustainable and ethical practices in all aspects of the business, from sourcing materials to manufacturing and packaging.

Clothing

Knix earns strong reviews for leakproof underwear that reliably prevents leaks, feels soft and seamless, and comes in multiple styles and absorbencies, but opinions on bras are mixed to poor, with frequent complaints about support and fit. Reviews also flag sizing inconsistency, tight waistbands and less-breathable fabrics, occasional coverage issues, and some users find washing and integration into routines cumbersome—useful to know if deciding between period underwear and traditional options.
