Knix underwear
I recently bought a package of knix 3 reusable period underwear. No way to try on I have found the to be bikini which on box does not say that. So now I have tried on 1 pair and the elastic waist curls and rolls down. I now have 2 pair which I cannot wear. This cost me $39.99. Please be advised that I cannot recommend this product. NOT satisfied. Cannot return to store

Life changing panties
I can not believe it took me so long to try period panties, I will not go back to pads. These underwear are so comfortable, I will definitely be buying another one or two.

These were not “no-show”, as the leakproof padding is quite thick - even at the lightest absorption level. It looks and feels like wearing a pad, and defeats the purpose of no-show underwear because the padding is visible through tighter clothing.

Fast delivery. Product quality strong as expected.
Fit and quality was great. Bought as a surprise colour 3 pack. Colours were unsurprising as they were all the same.

Good
I like the absorbency, but the cut isn't right for me. I wish the leg cut was the same as the high-waist, but don't want the waist as high as that one. They are comfortable and wash well.
