Quite big fitting

No, I don't recommend this

I found this colour and material different to the other colours, more silky and the size quite a bit bigger in fitting. I’ve bought quite a few of the other colour 3 sets and they were true to size but these are bigger, I should have gone down a size or two.

Size down!

Yes, I recommend this

These are a great idea and really comfy but, this particular style comes up huge. I had to get 2 sizes smaller to get a good fit. Would be better if they sold them individually. I had to spend £60 on 3 different sizes before I got to the right size.

Helps with incontinence

Yes, I recommend this

I bought these not because i have periods now, I am 63 years old and I have had a bad kidney stone, now removed and the stent in my kidney and bladder was causing urgency and slight incontinence. I have bought my normal size 14 ,but I would recommend going down a size as I felt they were a bit loose around the legs . There was a bit of a chemical smell to the pants but washing them first took that away . Very comfortable pants and even though I did leak a bit ,it was absorbed straight away. Far more comfortable wearing these , they feel like normal pants to me and nothing can be seen unlike pads . Putting my ordinary pants on top helped 'seal' the top of my legs making me feel more confident. However if this incontinence continues I will buy the size 12.I do recommend despite the pants being a bit too large.

Huge!!

No, I don't recommend this

These are huge! I should have looked at earlier reviews and got probably 2 sizes smaller! Also there is an uncomfortable, parallel seam at the back. The positive is the material is lovely and soft and won’t “dig in”. They will probably absorb well, but I’ve found them uncomfortable - could be because they’re so big!

Could be improved.

Yes, I recommend this

Good product, but would be better if the material was cooler, for the Summer. Cotton would be preferable. Also, the special lining in the gusset, seems to have a strange unpleasant odour after use. Could be better for light incontinence!

Love this new design

Yes, I recommend this

Absolutely love these new design pants! I bought them in black and wear them everyday wether on period or not. They eliminate any odour and leaks so they are perfect for daily use. The fabric is soft and has a silky shiny stretch to it and they are much more comfortable around the legs than the other styles. They are a perfect fit for me but suppose you could go down a size with them being stretch fabric. My drawer is now just full of these pants and all others are gone
