Excellent value for money !

Yes, I recommend this

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.

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.

Great all rounders.

Yes, I recommend this

Very comfortable knickers with a good level of absorbency. I like that these can be washed as normal - some other brands need to be cold washed. I am 36 weeks pregnant and find these well fitting, flattering and great for occasional leaks. Well done M&S!

Not great

No, I don't recommend this

For ‘full briefs’ they barely cover your bum! But cover an awful lot of your stomach! Not the style I was looking for, I’ve tried better brands with more appropriate coverage given the nature of the product. Only reason I’m keeping them is the colour as I can only find black ones elsewhere

Wonderful product but short on colours

Yes, I recommend this

Bought 2x 3packs of heavy absorbency knickers and they are great but you’ve stopped doing the lovely colourful ones. We don’t just need black and beige. Give us loads of colours and lace please

Perfect for sen needs

Yes, I recommend this

Was highly recommend these for when my sen daughter started her periods. We have been using them for years now. The quality and durability is a win for us. Comfortable, stylish and good value for money.

Disappointing purchase

No, I don't recommend this

Whilst the material and fit of these are excellent, they unfortunately do leak as the sides are so narrow. I also think the gusset could be thicker as they are too thin to hold much fluid.

i found the material too soft

Love these, but found the material on the pants too soft/flexible. Personal preference for a more solid material.

I have bought a few pairs of these, not for periods but for bladder issues, Highly recommend them more comfortable than pads and similar to normal underwear

Far too big

No, I don't recommend this

Purchased this product for incontinence rather than using pads.having purchased similar ones already. These pants are far too big which for not make them usable or value for money. More suitable for a larger person over 6 ft tall.
