As We Get Older

I don't know about men, but as women get older it is quite common to slowly become incontinent. Problem is they don't want to talk about it! ONDRwear has great products that really work. Yes, they are a expensive, but they do the trick. I highly recommend at least going to their website. You might learn a thing or two. Or at least pass this website on to someone you might know that is struggling.

Life changing

I have only been wearing these to the gym for a week and I can honestly say they are life changing. I am 37 and do not have children but for some reason, every thing I do at the gym makes me pee. I can only exercise at certain times and wearing certain pants and it's always a big mental hassle. I also can only workout in a thong and the other thongs on the market hold way less. These are so incredible and I am so happy I discovered them!! And the customer service is EXCELLENT!

If I had to critique anything, I would love for these to be available in a different material. The thong is so nice and soft/slippery that my pants don't stay up nearly as well as they do with cotton thongs. It's like the workout pant material and thong material don't work together but I don't care, I will make it work!


Love these non-toxic, leak-proof period-proof underwear! ... and always happy to support a female led business! THANK YOU.


OMG!! The thongs are great!! My sister suggested that I get some, I ordered 3 pair. No more accidents for me!! Thank you so much for the modern styles.
