What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
Customers say these period underwear are comfortable and feel like regular underwear, with many praising their leak protection and confidence-boosting qualities. Users appreciate the no-show design under clothing and find them effective for both period protection and light bladder leaks. Many reviews mention the bikini cut runs small, with several customers recommending sizing up for a better fit. Some note the underwear can feel tight around the waist or create visible lines under certain clothing. While most find them durable and long-lasting, a few mention issues with the newer versions feeling stiffer or having ridges where seams meet. Overall, customers value the comfort and protection these provide as an alternative to disposable products.

Great fit. On the expensive side for me on a fixed income.
DMDonna M. P.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 4 out of 5 stars4 days agoPerfect!
These have a great fit and the protection is wonderful. They do show in jeans but I use the super leakproof at night.
SBSarah B.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars4 days agoBikini Brief
Absolutely love and recommend them. I have quite a few pairs and they're the best decision I could've made. Super comfortable and I have no concerns about leaks. I have a very physical/demanding job and I can do it without concerns now

BSBrianna S.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 1 out of 5 stars1 month agoNot the slightest bit leakproof
Came right out the sides like it was water-resistant in there. So sad. :(
DIDeanna I.Verified BuyerReviewingSuper Leakproof® No-Show Bikini 3-Pack - Rated 3 out of 5 stars1 month agoThe material is different.
In general I like your bikini underwear but everytime I order the material is different from a heavier cotton to a thinner cotton to some polyester blend. I am not fond of them and feel they are not very breathable.
RLrenee l.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 month agoAs ever…
Knix work well for my leaky bladder. Just know that what they call bikinis are what most other brands call high-rise. (Their high-rise are granny panties.😁). Order accordingly.

MSMyra S.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 month agoLove them!
I discovered Knix about four years ago and I am truly impressed with their leakproof underwear’s. I recently reordered and noticed that they are even better quality than the ones I ordered in the past- locks in odor and dampness better than before. I only ordered 3 new pairs because they are expensive, but I’m looking forward to getting more in the near future-if they are on sale.
