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.

Let customers speak for us
from 1783 reviewsI 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.
Very happy with my purchase)
We tried other suits for our 6yo non verbal son but this was the only one he likes and can't get out of. Game changer!
As previously reviewed, in order to stop my special adult lad from removing his clothing three times a night in order to pee over his bed(!) we started in the summer with the sleeveless onesie and it took a few adjustments for it to work q.v.
But these are perfect. He cannot wriggle out of these; they are so comfy that he doesn't care that he can't wriggle out of these; and he only disturbs me overnight now if his diapers are at fault, not the onesie.
His regular clothes are 3XL yet the 2XL here is roomy enough that we don't need a custom order👍.
And now that winter is coming we can simply add warmer over-things if we need to. (Queensland here, we won't 'need to' that much!)
We went from three loads of washing a day back to normal clothing loads. Oh, some weeks now I have to remember to purposely give him fresh bedding like for the rest of us!😂
Has Changed My Life! Thank you so much. Absolutely pays for itself in savings on power and water bills. This may not be everyone's problem but it sure was mine and I'm happy it is solved.
This is the third time we have purchased these pants from Night n Day. We use them as overnight pants for our son (instead of disposable night pants) and have only had them leak once in 2 years of using them, so probably not suitable for heavy bed letters but more the kids training out of night pants or where you need extra piece of mind.
If you need these urgently, please note that distribution can be a bit delayed, so best to plan ahead. We get about 12 months use out of a pack of 4 rotating through the week.
These are made really well , they were too small for my son .
This product prevents rashes and chaffing, it holds well and prevents accidents from being noticeable or visible to others. If soiled it is easy to clean. I recommend this product to everyone that’s talks to me about Continence issues. Really supports my son with building independence with hygiene and toileting.i recommend purchasing one size up due to the thickness of the stitches in liner.
