I've wondered for years why women didn't have an option for boxer shorts. Boy shorts later came out, and they were fine, but I wanted something to cover my upper legs. Knix Dream Shorts are the dream answer! I know Knix creates period underwear, but I'm past that age now. I'm in the light bladder leak age of life. I'm thrilled to announce that the Knix Dream Shorts work wonderfully on light bladder leaks also! The padding is thin, absorbent, comfortable, and conveniently long. The fabric of the underwear is silky soft and feels like it isn't even there. Knix Dream Shorts are my ideal underwear! I cannot recommend more highly.

How to wash
Machine Washable: Wash with like colors, cold setting with mild detergent, do not bleach, iron, or dry clean.
Always refer to our Fabric & Care section for best drying practices.
Your leakproof questions, answered.
Our Leakproof technology features a built-in absorbent liner. Depending on the style you choose, the absorbency can range from about 1-17 tsp of liquid. The result? Confident protection from sweat, discharge, periods, and light bladder leaks.
A gusset is essentially a liner. It’s where you’ll find our leakproof technology. It’s built into the crotch section of the underwear.
Coverage at Knix comes in all shapes and sizes. If we’re talking about silhouettes,, we go all the way from thongs to boxers.
We also offer high rise styles, like the Leakproof UltraThin No-Show High Rise, that sits just above the natural waist and gives full coverage through the stomach, hip & bum.
For extra liner coverage, look for undies that have an “extra-long liner” (usually 10”-14”), like in our Dream Short. And our Ultra Zones+ also have full bum coverage, too.
Have a suggested style or coverage? Just let us know. We love the feedback!
Leakproof covers you for all of life’s leaks, like periods (including your heaviest flows), sweat, light bladder leaks, postpartum, and discharge.
