Fun colour, great absorption!
These undies are so comfy! They have washed and maintained their shape well. Functional and a bit of fashion fun with the pop of coral colour. Highly recommend.

Brilliant! We are happy to hear that you love them! Love from team Hello Period xx

The best fit!
These undies are so comfy and the quality is exceptional. They have washed and maintained their shape well. The pad bit does not get all scrunched up or lumpy, so subsequent wears after washing and drying them is as comfortable as the first time I tried these panties. Highly recommend.

Best period ever!!
Wow, I have been through so many changes to my period after having 2 children and I'd have to say that my first time using these undies was the most relaxed period I've ever had. I always thought there had to be a better way and these are it I use them for my first heavy day(s) and then a cup for the rest but I might end up the undies the whole time. I had no anxiety over leakage for the first time in my life, they are so comfortable and absorbancy is great, I didn't feel like I even had my period (apart from the cramps). I am so grateful I tried them and while I know they might not be for everyone they have made my period experience better than any other product I've used. Thank you!!!!

This is fabulous to hear! We know that the Undies have great absorbency ratings, but it always the best thing to hear a customer say exactly that! Thanks for your review! Love from team Hello Period xx

Hello Period
The fact that you used the word "relaxed" is brilliant. We really love to think that our customers don't have to worry about their period and the threat of leaks! Love from team Hello Period xx

Good and true to size
Good fit, true to size. Both my daughter and I have a pair. The fabric is like wearing togs which is fine except on hot days. Love that they're easy to wash and dry more quickly on the line than other brands.
Hello Period
Yay, sounds like that are a good fit. Some people do seem to find that the fabric keeps them warm. Thanks for sharing! Love from team Hello Period xx
