Come out very big

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I purchased a size smaller than I usually wear. They were very big and kept pulling my trousers down. I ordered another set but again went down a size and again they are far too big. They are also nylon and are very hot

I love these pants. They are so soft and comfortable to wear. I wear them as an older person with bladder issues.

Alternative use

My relative has bladder issues. She feels really secure wearing these with incontinence pads because of the thickness and absorbency they have. Better than incontinence under wear which is plastic and uncomfortable.

Comfortable and reliable. Life changing product not only for periods but for incontinence too. Please make ones in white, too and add femininity to enhance.

Great Quality & Value

These pants are ideal for people with urinary problems doing away for the need of pads & panty liners. The material & look is far lighter & nicer than previously. Would be even better if the gusset matched the colour of the pants as with the black pairs

Theses seem expensive compared to other brands , but the price quickly becomes worthwhile when you realise that these do exactly what they're supposed to do , while looking nice and feeling extremely comfortable as well.

Not heavy absorbency.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These knickers are a lovely silky material. They fit nice, and look just like normal knickers. I bought them to help with minor leaks, due to age, not for period protection. They are supposed to be heavy, absorbency, but I doubt they will cope with heavy periods.
