Comfy and they seem to be ok for day 3 onwards. Not super heavy days.

A bit disappointed.

Originally posted on marksandspencer.com (UK)

These pants are a very good idea however they come up quite a bit larger than expected and are quite uncomfortable. I will keep them in the hope they will shrink a bit

They have changed them.

Originally posted on marksandspencer.com (UK)

I bought the 'white mix' 3 pack (with white dots). They have changed the way they do the leg elastic - they have a thick edge and 2 rows of stitching, also the waistband elastic is different and irritating. Not sure why the change? I didn't realise, put them in my drawer and found out too late to return that they are different and not an improvement. This keeps happening, something you rely on and were happy to discover gets changed with no warning - sigh. Still wearable(needs must) but not happy with the changes.

Not the same.

The 'black mix' with the leopard print pair are very good - comfortable, well fitting and good absorption. However, the other set with the white dotty pair are not a good fit - they are tight on the thighs and the elastic used in the waistband is very irritating to me.

I found them really comfy and not too hot for the warmer weather unlike some other brands I tried. Will get some more!

I wasn't convinced about using period pants but after trying them, they are amazing, no leaks, easy to wash and comfortable.

Not the first time I've bought these for my granddaughter. She loves them. They help give her confidence especially on her heavy days.

These are very comfortable and absorbant. I have been wearing them both as a back-up with a menstrual cup and on their own overnight on occasions. I'm definitely going to buy more for the future.

So comfy to wear and has great absorption. A lot better than traditional pad as I usually get nappy rash with them.

New and improved - these are so much better than the previous ones I purchased. They fit better work better and are easier to wash and dry - thanks M&S for giving me my confidence back. Any thoughts on introducing a urine equivalent?

comfortable but offer little protection

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

these knickers do not give you full leakage coverage! if you gush, these provide absolutely no protection at the back. i will say they are true to size and they are comfortable but they are not suitable for a heavy flow

Perfect fit. Giving me extra security. I’ve been wearing this whilst wearing sanitary protection as I’m a very heavy bleeder
