How to care for your period underwear
Caring for your period undies is simple and easy. Follow our care instructions to ensure your period undies last a lifetime:
- Rinse: After use, rinse the underwear using cold water. Avoid hot water, as it can set the stain and make it harder to remove. You can soak if preferred.
- Wash: Wash your period underwear in cold water on a gentle cycle. Steer clear of fabric softeners and chlorine bleaches, as they can damage the fabric and reduce the absorbency and waterproofness of your undies!
- Dry: Hang the period underwear to dry, or if you must use a dryer, always use a low-heat setting.
By following these simple care instructions, you can keep your period undies in good condition and ensure that they remain comfortable and reliable for many cycles to come.

from 1834 reviewsComfortable & give me confidence I had lost with the fear of leaking, definitely purchase more!
Got these for nighttime wear. Most of the other options I have tried have failed either with loose legs or not enough coverage front and back. These pants are great. When I first tried them, they seemed too tight (biggest size available), but I have adjusted now and they feel nice and secure. The only thing I would prefer is that I could get them in White or Grey.
It got here before my holiday when i needed it and it held to its standerd for the night and the car trip.in the day
I love these swim pants.
If I am having a 'flare up' I know I can still go swimming and not end up in an embarrassing situation.
So I feel confident and reassured at the pool.
Thank you
Wish I knew about these sooner. Order size up as they are smaller than normal sizing.
This product has helped reduce the need for bed changes overnight.
I was an awkward patient, leaving before I was ready to. The nurses were fantastic and right in saying I was not ready to go home. I sincerely apologise for ignoring them, and I had to return a few days later when my penis blocked with blood. I of course returned immediately.
I love my adult pilchers especially while making long train or plane trips. They have saved me from many potential embarrassing moments and are great for wearing at bedtime.. I have no hesitation in recommending them for incontinence problems
This really is waterproof and does protect the bedding which is why I ordered it.
Another great product.

If you're a parent, you know that when it comes to nappies—especially swim nappies—there's no room for compromise. And after trying every brand under the sun (and moon), I can confidently say: these swim nappies are the legendary champions of leak protection, comfort, and convenience.
The products are described accurately. I get the absorbency I need and the accompanying peace of mind by knowing that I am not leaking. The prices are fair, their service is excellent, their news updates are good, and the shipping is good. Night n Day is simply the best when it comes to reusable incontinence products. Thanks!
Discreetly hidden liners and it looks just like a normal pair of underwear.
This product has given my son the confidence to attend school camp, without the need to send additional clothes or sleeping bags & because they look normal the other kids don’t know
When I purchased my shorts, I did not realize that there was a skorts product. I added a skirt to mine as I felt that the pad was visible.
I feel that the incontinence pad was too large for me as during my rehab as I did not need it at all, but I could have. It also took too long to dry before I had to use it again (one day break between sessions). It would be advantageous for these pads to be removable so that a dry one could be inserted when one was not dry enough to use. Different strength pads could then be used too.
