Over the past decade, Knix has revolutionized the world of intimate apparel, starting from modest roots and evolving into a leader in innovative leakproof underwear. Since creating leakproof underwear in 2013, Knix has reshaped the way we think about undergarments.

Joanna Griffiths founded Knix with a vision to reinvent the women's underwear market, paying close attention to customer feedback to better understand what works and what doesn’t in current offerings. Knix's mission has since been to create game-changing, leakproof intimates for every body type, empowering people to feel confident in their skin and live without constraints.

Beyond underwear, Knix offers a variety of products including wireless bras, loungewear, activewear, and swimwear. You can also take advantage of bundle deals to get more value for your money. Plus, Knix offers free shipping on all Canadian orders over $100. Visit Knix's page on Rakuten.ca to find promotional deals and earn Cash Back on your purchases.

With Rakuten.ca's Cash Back rewards and bundle offers, you can update your lingerie collection with stylish and functional pieces.โ€‹โ€‹โ€‹โ€‹โ€‹โ€‹โ€‹
