- June M.Verified Buyer2 days agoRated 5 out of 5 starsFinally! Thank you!
I’ve been hoping Knix would create a leakproof sleeping bottom for some time now. I really don’t like having to wear underwear under pajamas and this sleeper boxer is a great product. I just got it yesterday, wore it last night, will wear it again tonight. It fits well and performs even better. I just wish it were a little longer. Please make this product available in capri and pant lengths. I will definitely purchase at least one more boxer but I would buy LOTS of them if they were available in other lengths. Thank you Knix!

These are the most comfortable of all the products you make. The material against your skin is so soft- even the leakproof material. No agitation at all with this product! Wear at night and during the Day!
Love it !

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!
