★★★★★I got caught out twice by cheap copies before finding Ultradries. Fourteen years of a weak bladder and daily pads had my skin permanently sore. I didn't believe underwear could replace pads but I was desperate. Wore them for a week and the soreness was already going. Washing is easy, they go in with my normal load. I wish I'd found them sooner.

What materials are they made from?
Our underwear is made from premium bamboo and cotton fabrics with no harmful chemicals. The outer layer is 95% bamboo + 5% spandex, while the lining is 95% cotton + 5% spandex for ultimate comfort and breathability.
How much liquid do they actually hold?
Each pair absorbs 3 to 4 disposable pads' worth of liquid. For heavier protection or nighttime use, you can add our Organic UltraPads on the checkout page to triple the capacity.
Do you have nude colors?
Yes! We offer a discreet nude/beige color that's perfect for wearing under light-colored clothing, white jeans, or summer dresses. It's completely invisible under any outfit.
You can choose size and color in the checkout page.
What if I need to change when I'm out in public?
You don't need to change the entire underwear. Just swap the reusable booster pad in any restroom (takes less than a minute). Put the used pad in your waterproof wet bag - it blocks odors completely and looks like a regular makeup pouch. Or, if you prefer, the underwear itself holds 100ml so most women wear them all day without needing to change.
How do I wash and care for them?
Super easy. Rinse in cold water (optional), place in the included washing bag, and machine wash with your regular laundry. Hang to dry. The washing bags keep everything hygienic and separate. They last for years with proper care.
How long does shipping take?
We're experiencing record demand! Orders are processed within 24 to 48 hours, then delivery takes 7 to 9 business days. You will get tracking as soon as it ships.
What if they don't fit? 30-Day Exchange Guarantee
We offer a 30-Day Size Exchange Guarantee. If the fit isn't quite right, contact us within 30 days and we'll send you a different size free of charge. No need to return the original pair - you can pass it along to a friend or family member who might benefit.

I wore these under white linen pants to a wedding last weekend. WHITE PANTS. Something I haven't done in four years since my bladder issues started. No leaks, no visible lines, no anxiety. I danced, I sat through the ceremony, I laughed through the speeches. Nothing. Not even a damp.
Christine M. ✓
Love it!
Barbara C. ✓
I was worried they would feel like a nappy and they honestly do not. They feel like normal cotton underwear. Three weeks in and my skin has stopped being sore.
Barbara Y. ✓
After about 3 days of wearing Ultradries I started to notice I wasn't constantly worried about leaks anymore. By the end of the first week, I'd stopped carrying emergency pads in my purse.
Now after almost a month of use, I feel completely normal again.
Carla O. ✓
Don't worry about washing. Rinse if you want, toss in the washing bag, throw in with regular laundry. Hang dry overnight. That's it. Easier than I expected and they've held up perfectly after 6+ months of regular washing.
Carol J. ✓
A leakproof underwear that actually does what it claims. Very comfortable for all-day wear, doesn't show under clothes, and genuinely holds leaks without feeling damp. No odor issues even after 8+ hours.
Janet W. ✓
Very happy with these! The fit is good and they are comfortable. Thank you!
Kim S. ✓
They work. Period. If you leak, buy these. Stop overthinking it. Three months in, zero leaks, zero regrets.
Evelyn R. ✓
Writing this review after 14 months of daily use. I have 12 pairs that I rotate through and wash weekly. After over a year, they still work perfectly.
Virginia K. ✓
I was terrified these would be bulky like adult diapers. They're not. At all. I wore them under fitted jeans and my daughter had no idea. They’re thin but powerful - no visible lines, no bulk, no noise when you walk.

Customer Reviews
Love the feel of fabric. Sizing way too big at leg holes! Should have ordered smaller or maybe a petite, which was not offered. Please exchange. I waited from ordering in August to mid September to receive.
