Best pants on the planet

The BEST pants I have ever had. A game changer, a life saved. I’ve bought so many pairs but size down! Nog just period pants but for those with ‘urge incontinence’ - can’t praise them enough!

These period pants are terrific. I read about them and decided to try, they are so comfortable and I feel confident wearing them. I definitely recommend.

Great absorbent knickers.

Originally posted on marksandspencer.com (UK)

These are good knickers if you have a weak bladder as they are very absorbent. I am a mature woman who likes to feel confident when out and about and don't like wearing thick sanitary pads. They also look quite attractive if you buy the coloured ones.

I bought 2 packs - one for me and one for my daughter. I found the pants to be comfortable and effective. My daughter (age 15) was less keen and said she did not find them suitable for heavy days.

Great Outcome

Originally posted on marksandspencer.com (UK)

These worked very well for me, very pleased. I usually have quite heavy periods for the first few days and it affects my sleep because I have to wake up to change in the middle of the night. However, I tried these and they are very comfortable and worked quite well. I still can’t sleep as long as I’d like to but I can at least sleep for 5 hours before feeling like I need to get up.

Comfortable and good absorbency. Better than the ‘super heavy’ underwear. Would definitely recommend these and will purchase more.

Terrible absorbency

Originally posted on marksandspencer.com (UK)

I am so disappointed in these! I bought three packs after reading a review in a newspaper and these came out on top. I do not have a heavy flow and these leaked at a ridiculous rate. I need to find out if I can have a refund. What a waste of money.

Good quality but useless if you want to wear pads

Originally posted on marksandspencer.com (UK)

Ok so pants are the usual M&S great quality, BUT assuming you want good absorbancy, you might want to wear pads with this product - the pads don't stick to the lining!!!! fundamental flaw I would have said!!! Also the seam across the back of the gusset stops the fabric stretching so it's uncomfortable and at times visible through trousers. Not their best product.

I thought they would have cotton lining but they do not and the lining irritates me.

Really please with these. I was looking for period pants that look and feel more like normal underwear. These are very good, much less bulky and love the colours.

I bought these for my Granddaughter, she can always have a spare pair of pants at school if needed. I thought the pants and bags were a really good idea.
