    In love!

    I love these thongs, I ordered 3 on sale and now I want 20 of them! I hope they come out with more colours! I'll buy them for sure.

    Excellent!

    My first time trying out the Knix cotton thong and I am pleasantly surprised with the comfort and leakproof control! After having my kiddo, having a small bladder and a pelvic wall that is actually too tight, I experience daily leaks and often forget to put in a liner. These thongs keep me dry and odor-free without looking like Granny-panties! Lol. I'm just about to order more!

    Love Cotton!

    Great comfortable material with great stretch. It’s a thong but the front and liner still provide coverage!

    My new knix fave.

    So comfy!

    Love these so much that I came back to order more, but was reminded that there isn’t a wide selection of colours. I already have the black and brown and I won’t ever do white, so now I won’t be ordering more because a bunch of black and brown undies is not very fun! Pretty please make these in more colours! Maroon? Dark green? Navy blue? Red? Fuscia? Anything!!

    Love the feel

    These are very comfortable and fit well. I like that they’re cotton, wont wear anything else. Wish they were offered in better colour selection…. Maybe Navy or Hot Pink. Overall really love the feel of these thongs and would buy more if they came in a better variety of colours.
