soft and comfortable

Yes, I recommend this

I found the material soft and comfortable , as I wanted them for any slight leakage of urine which I suffer from now and again they were ideal, however , I would not trust them to hold back leakage of a heavier nature , such as a heavy period .

Excellent

Yes, I recommend this

Changed from incontinence pads, which were uncomfortable to wear, to these briefs and incontinence has virtually disappeared. I change them twice a day and they are much more comfortable, day and night. Have ordered 3 more packs of them.

Good quality overly large I bought a size down

Yes, I recommend this

Good quality and absorbency I found them to be so big I bought a size down from my normal and they are still quite large. I’d personally prefer an all cotton version that said these do what they say, work well and I’m very pleased with them

Happy with them!

Yes, I recommend this

Perfect for me! I use them alongside a tampon or alone when my flow is very low/spotting. Keeps me fresh, no leaks and easy to clean. Would recommend.

Pants perfect for mild incontinence

Originally posted on marksandspencer.ie

Yes, I recommend this

As an older woman nearing eighty, I bought these pants to avoid having to use panty liners for mild and infrequent urinary incontinence. I have a bladder diverticulum that sometimes causes mild leaks. These pants are perfect for my problem. I bought a smaller size than I would expect to use as I had seen reviews saying they were too large, so I bought size 14 and I am a 16.

Not as good as hoped

No, I don't recommend this

I’m surprised so many people have said these are great. They barely absorbed anything and found having to change them 2-3 hours later and they leaked out the sides. Suppose would be ok for lighter days
