Repeat purchase

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.

Yes, I recommend this

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.

Fantastic

Yes, I recommend this

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

Yes, I recommend this

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

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

Good quality pants

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.

Im recommending to my friends

Yes, I recommend this

First time to try this underwear and they did not disappoint. Made me feel so much more confident when I'm out and about. I was always worried about coughs and laughing but these are genius. They do not feel bulky but are heavy enough to make you feel secure. If they go down in price I will get another pack as £16 is just out of my range to get stocked up

VERY SATISFIED

Yes, I recommend this

Very pleased with this product and glad that I saw the advice from another review to err on a smaller size as the fit is generous. I was nervous at first when a small leak occurred as to whether they would do the job I hoped for. Happily they are fine and thankfully seem to last the day without an apparent odour. I now own 15 pairs. My only constructive criticism is that M&S don't sell an individual pair of each size as a test purchase. £16 is a lot to risk if not a good fit or they don't satisfy the customer. Also I would prefer a single colour (I'm not a leopard skin person at 74!!!) and not really black either. I would have liked more choice of colour availability. Otherwise love them, very comfortable, the full brief size is great and no tightness.
