As our team of midlife moms has discovered, perimenopause and menopause brings many delightful changes to your body. Bet you didn’t know that bladder leaks or unexpected discharge would become part of daily life— did you? Luckily you don’t need to wear those diaper-looking-underwear of the past. Modern, leakproof underwear has evolved into lightweight, comfortable, practical choices that you’ll be fine to wear every day (and night). The brand Knix has become a leader in the space (thanks to Joanna Griffiths— yet another reason we need more women in charge!). Below are three menopause-approved leakproof underwear picks from Knix, so that whatever happens (laugh pee, etc), you’ll be just fine.
Top Leakproof Underwear Picks from Knix
1. Knix Light Leakproof No-Show Mesh Bikini Underwear
Best for: Light leaks, discharge and regular wear. Laugh pee sometimes? Perfect.
These underwear are light and seamless, the wicking fabric feels thin so you can wear these everyday. This is the bikini style, but they also come in high-rise if you want more coverage.

2. Knix Leakproof Cotton Bikini
Best for: Moderate leaks, like laugh pee, discharge and/or spotting or still getting your surprise period sometimes.
If you only wear cotton and need some leak protection, you’ll like these bikinis. They’re considered ‘moderate’ absorption so whether you laugh pee, or are spotting, you’ll feel good in these. They don’t feel like you’re wearing a pad, but they do feel like more than undies.

3. Knix Super Leakproof No‑Show Boyshort Underwear
Best for: Moderate to heavier leaks. Your damned period keeps coming. Or it’s incontinence. These work.
These underwear are seamless and they definitely retain the leaks. They have a 9″ built-in liner and hold equal to 1.5 regular pads.

How to wash/launder leakproof underwear
I used to be precious and hand wash undies and bras in the shower or sink, but who the hell can do that as a mom. I throw them in the laundry with everything else, but I do hang these to dry. On the laundry rack, over a door knob whatever..they last so much longer and the last thing you want is for them to shrink and feel tight. I know some of you are squeamish about liquid/blood but if you haven’t gotten over it by now, you have to. These can go in the wash with other things, but if you really don’t want to mix, then do these every day or two on their own in the smallest cycle your washer offers.
Final Tips for Menopause Leak Protection
- Match absorbency to your needs: Light absorbency works for mild leaks or discharge, heavier options are better for stronger bladder leaks or overnight wear.
- Comfort matters: Choose breathable, soft fabrics that feel good for all-day wear.
- Pair with other solutions: For extra heavy days, consider pairing leakproof underwear with pads or liners.
Modern leakproof underwear combines function and comfort so you can live confidently — without constant worry about leaks interrupting your day or night. They are seriously the best invention! As good as period panties for tweens and teens!
