Got bladder issues? They’re nothing to be embarrassed about and quite common, especially as we age. According to Harvard Health Publishing, one in three women experiences this to some degree by age 40. Of course, you should consult your doctor if you experience this regularly, but you can also arm yourself for day-to-day comfort.
I’m sure you’ve heard of period panties —namely, ones by the ever-popular Knix brand — but you know those aren’t just for a menstrual cycle, right? The beloved leakproof undies can also save the day if you experience urine leakage, too! Best of all, Knix just took 30% off all of the brand’s famous leakproof underwear for its sitewide Anniversary Sale, dropping the underwear to as low as $16. That’s a dang fine deal for protection against everything from light bladder leaks to extra heavy period days. (By the way, the discount extends to all underwear styles, too, including thin no-show high rise, bikini, boyshorts, boxer briefs and French cut.)

While Knix is best known for selling period underwear, it’s worth noting the brand has also become a go-to choice for anyone experiencing bladder challenges, especially when wearing adult diapers doesn’t match the vibe.

The company offers underwear that ranges from light protection (withstanding 1 to 3 teaspoons of liquid, minor sweat and discharge) to ultra protection (preventing leakage for up to 17 teaspoons of liquid).

Unlike adult diapers and menstrual pads, reviewers say Knix’s undies are so comfortable, they often forget they’re wearing any at all. Take it from one shopper who swears by the no-show high-rise underwear: “I’m 78. Sometimes my medication makes me sweat, sometimes I sneeze and pee a little. I refuse to wear adult diapers for a small problem. […] Love the material and fit!”
The brand offers various styles in sizes S-4XL and in five absorption levels of leak protection. Here’s an easy breakdown:

That leakproofing is serious, too! According to one reviewer named Bethany: “My water broke while I was wearing these and none made it through to my pants. Nurses were very impressed with them and I can say these underwear were worth every penny.”
Still, if the idea of leakproof underwear seems strange or gross from your perspective, it’s actually much more sanitary than it sounds.

Knix underwear features a stain-proof gusset that’s packed with technical fabrics (similar to workout clothes) that absorb, hold and wick away liquids, helping you feel nice and comfy when you’re experiencing a leakage of any kind. And the mateiral is wash cycle-friendly to boot.
(Making the switch is also the more economical choice in a soon-to-be more expensive post-tariff United States. You know we have to point this out.)
