Knix period underwear and pads are now sales tax-free in Canada.* We celebrate improvements to the accessibility and affordability of essential period care products.

• So thin, you’ll forget you’re wearing anything. Our original leakproof technology offers a barely-there feel while absorbing about 1 regular tampon or pantyliner worth of liquid.

• Patented bonded edges help prevent against side leaks.

• The carbon cotton gusset top layer wicks away moisture from your skin.

• These underwear feature our signature buttery soft fabric.

• No show construction is designed to be invisible under clothes, including workout leggings.

• Machine washable just like regular underwear.

Our original leakproof technology is perfect for everyday wear (think sweat, discharge and light leaks), backup protection during heavier days or on its own for lighter days.
