    Comfort in confidence

    I wear these to protect against light bladder leakage and hey are seriously a game changer. I can walk around all day, take long buses (that don’t have bathrooms! 🫢), go to the gym and never feel self conscience about leaks. I used to use liners (reusable ones and disposable) but, aside from needing to carry fresh and used ones around or adding to the global garbage crisis, they never made me feel as “safe” and confident as these underwear. This style in particular is literally just like my regular underwear - no extra bulk anywhere, which is great once you’ve hit a “certain age” and temperature regulation is KEY! These are the “secret, sexy undies” to help you feel confident and unstoppable 🙂.

    Comfy cotton

    If you don’t like the slippery no show fabric, these are a great alternative. Love having these in my rotation. Super comfy and reliable.

    Cotton modal is the best!

    I love the cotton modal fabric. It's the best! It's super soft, light and absolutely no sweating. They are so comfy that I hardly know I'm wearing underwear! I can't wear anything polyester and it seems like it's everywhere these days. I was so excited to find these in cotton modal. I bought one pair and within hours, I ordered three more pairs before the sale was over. I have a light bladder leak and these are my saving grace. I love the high rise fit and will definitely buy more. (I tried to order more recently, but couldn't find them on the website. I hope they have not been discontinued. That would be devastating!). Please restock and bring in some lighter colours for summer.

    Prefer other Knix undies.

    They sat a little too low and shrunk in the wash.

    Leakproof padded panties

    These are just great. Fit well, great fabric, appropriate padding. They are also very comfortable.
