Introduction
Finding underwear that truly feels comfortable, offers optimal functionality, and celebrates the diversity of body shapes is rare. Knix fills this gap with underwear, bras, and sportswear for everyday wear, specific needs (such as leak protection), and inclusive sizes. Whether you’re looking for high-quality basics or functional underwear, Knix offers a thoughtful combination of comfort, technology, and style.
About Knix
Knix was founded with the goal of reimagining underwear for women and all people with different skin tones. Away from one-size-fits-all and impersonal marketing brochures, towards comfort, function, and acceptance. The range includes leak-proof underwear, wire-free bras, sportswear, and loungewear. Over time, Knix has built a reputation for combining performance fabrics, intelligent fit, and campaigns that promote a positive body image.
Knix's Mission & Philosophy 🌿
Knix operates according to the following core principles:
Comfort first: Soft, flexible fabrics that move with you instead of restricting your movement.

Confidence: Underwear you feel good in – for a life full of energy, freedom of movement, and self-confidence.
