Work very well for minor bladder problems.

They are tighter fitting around the legs than those in the three pack. The main body of the pants are double lined so not really suitable for Summer wear.

I have bought several pairs of these knickers. They are so comfortable and give me so much confidence. They are definitely the best knickers I have ever bought. I have recommended them to all my friends.

Poor Quality

Very poor quality, the leg elastic although not tight leaves red wheels on your legs.

Super comfortable in the hot westhet

So comfortable and cool because of the cotton content. Would be nice if they were available in pale colour as well to go under summer clothes. They are reliable and fit really well.

Big pants

Originally posted on marksandspencer.com (UK)

Sorry but I thought these were awful.I bought two packs & because I tried out one pair could only send one pair back.They felt as if the thicker gusset was too short at the back & with no stretch in the main material felt as if it was hanging down & so uncomfortable I have discarded them.⁰

Great knickers , thicker than previous types but sizing better . I like the colours , white and nude would be good to match current bras . I like that they're cotton mix , much more comfortable .

These are the best value I have found for this type of pants. They do the job perfectly. Fit is good. Comfortable too.

Not a good fit.

Originally posted on marksandspencer.com (UK)

The soft cotton is nice and the absorption level is good but the fit of these knickers is very poor. They are tight around the thigh but very baggy around the waist. Other products in the M&S absorbency range are much better in my experience.

Great For ‘Whoops’ Moments

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I buy these for ‘whoops’ moments rather than for use as period knickers and they do the job perfectly. I bought them in a size 16 for comfort (I am between sizes 14 and 16) but I prefer them a bit loose rather than too tight. They are well made and wash well. My only observation are that the darker grey knickers are more a mid-denim colour which I am not a fan of and also it would be good to have more colours available. Otherwise, highly recommended.

Not the best

Originally posted on marksandspencer.com (UK)

Different to the cotton period briefs I’ve had before which were excellent thin cotton and more or less invisible under clothes. These however are heavy ribbed material and remind me of the school knickers I had to wear in the sixties. The size was accurate but the elastic left red marks on my legs and around my waist. They do the job hence 2 stars but in my opinion they are drab, the fabric is too thick and the colours unimaginative. Please bring back the flesh coloured cotton mix ones sold in a 3 pack.
