Perfect

Yes, I recommend this

Brilliant and dare I say life-changing? Will not be going back to disposable pads. These are comfortable, very absorbant, easy to wash, discreet and much better for the environment.

Bought for inflammatory bowel disease leaks. Excellent fit and comfort level. Would like to be able to stick a pad inside for extra protection.

Excellent quality and fit

Yes, I recommend this

I love these period pants - they keep me secure, comfortable, and confident all day and save me a fortune on period products. I've bought several packs across a couple of different fits to suit me across my period and they work like a dream.

Better than expensive brands

Yes, I recommend this

I wouldn’t normally write a review for underwear as I think it’s really subjective, but these are really great. I previously bought some of the expensive ones you see all over instagram and they were so uncomfortable, really tight and sweaty. These M&S ones are perfect, don’t feel much different to the same style non period ones. Didn’t have any leaks. They washed well. I couldn’t ask for more, thanks M&S, good job well executed.

Period Pants

Excellent quality and comfort and purchased for slight urinary incontinence. Definitely need to size down as they are a very large fit but I have still given them a 5 star rating as I am very pleased with them and will order more in the lesser size.

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

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.
