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

Comfortable and absorbant.

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

Good quality pants

Originally posted on marksandspencer.com (UK)

Read reviews and thought I would try. Quality is good as is sizing but find pad does not always stick very well to pants. However, I will continue using as I am not mobile at the moment.
