Frequently Asked Questions
Is it hygienic?
+
Yes, our incontinence underwear is hygienic. It features a special antibacterial layer. This layer helps kill bacteria and eliminate odors, keeping the underwear clean and fresh throughout the day.
How long can I wear the underwear?
+
Our underwear can be worn for up to 12 hours, but this may vary depending on the severity of your incontinence.
Won't it smell?
+
No, definitely not! Thanks to the special antibacterial layer, any unwanted odors are eliminated, keeping our underwear fresh all day long.
Doesn't it feel wet?
+
No, thanks to our special 4-layer technology, our underwear absorbs all moisture, so it doesn't feel wet on the skin.
Doesn't the underwear feel "bulky"?
+
No, most women don't notice the thickness of the fabric while wearing it. Only the absorbent part has extra layers, which makes this part of the underwear slightly thicker, but not in an annoying or noticeable way. The rest of the underwear is just as thin as regular underwear. This ensures you feel protected against leaks without discomfort, and it's breathable, unlike panty liners and disposables.
How many pairs do I need?
+
We recommend one pair of underwear for daytime and one for nighttime. A minimum of 4 pairs is recommended, so you always have clean underwear for the next day and have time to wash your used underwear.
How do I choose the right size?
+
To choose the right size, you can use our size chart above. Generally, you can use your regular size. Most women find all our underwear fits well.

These feel like proper underwear.. soft, secure, and not bulky at all. I wear them throughout the day and don’t find myself constantly checking anymore.

I’m still working full-time and constantly on the go, so the last thing I need is worrying about leaks during the day. I tried a few different options before this, and most either felt bulky or just didn’t sit right under clothes.
