Love Knix leak proof bathing suits
No fear of embarrassing leaks by the pool, ocean or dock. Thank you Knix! Also the prices are excellent as is the quality - love the colours too!

Perfect fit
Perfect fit, not too tight and doesn't create a bulge at the waist line. Haven't used it for period protection yet, but I'm confident given all the other Knix period underwear work so well.
