Product Description

The comfort of a boxer with the power of a pad. The Super Leakproof Dream Boxer offers a relaxed, non-restrictive fit that makes it the perfect choice for lounging and sleeping. Whether you’re managing a heavy period, postpartum recovery, or light bladder leaks, the high-rise waistband and soft-touch fabric provide a supportive feel without digging in. Designed to replace bulky pads and liners, these absorbent boxer briefs offer a solution for your monthly cycle. Available in inclusive sizes XS to 4XL.

Comfort-First Fit

Combining a loose-fitting boxer with an internal brief for discreet Leakproof protection. Designed to be worn as both loungewear and overnight protection.

Worry-Free Protection

Designed with a built-in leakproof liner that fits snug to the body, it helps lock in leaks from every angle, even as you toss and turn.

Heavy Absorbency

Absorbs up to 8 super tampons. Great for heavy flow days, overnight protection, and light bladder leaks.

Easy to Wash

Machine washable, just like your regular underwear.

How do I find out my absorbency level?

Are Leakproof products tax-free?

Which styles have more front or back coverage?

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 Super Leakproof® Dream Short™ and our new SuperPlus Leakproof® Collection with our longest front-back-liner.

Have a suggested style or coverage? Just let us know. We love the feedback!
