Great absorbency. They work exactly how we wanted.

Yes, I recommend this

These period pants were purchased for a young girl with texture issues and someone who couldn’t cope well with sanitary products. They have really made a difference. I can definitely recommend them. We have bought two different styles and both are equally great.

We've bought many Pairs of various brands and these one shot a thumbs up from my girls. Comfy and not too bulky. They are more confident in these, will definitely be buying more of them.

Good quality

Yes, I recommend this

I cannot believe they are called first period shorts and they are sold in adult sizes!!! I had to guess which size would be suitable to my 12 year old daughter. Can you please get the sizing right or at least do some research on when girls get their first periods (roughly) Otherwise the quality is good and they do the job especially at night

Fantastic

Yes, I recommend this

I’m 31 and I use these so they’re definitely not ‘first period’ shorts! Super comfy and made of good quality. Would recommend.

Look good and great for daughter’s confidence!

Yes, I recommend this

Bought a size 4 for a slim 12 year old, they fitted fairly well and gave much needed confidence handling her menstrual cycle at school. I agree with other commenters that there should be more coverage towards the front and less right at the back, but they did the job and would recommend.

Great

Yes, I recommend this

Bought for my 13 year old who wanted to give period pants a try as a more sustainable and convenient alternative to disposable pads. She was a little unsure about how absorbant they would be but she was actually impressed with them and found them less of a hassle to rinse out than she had expected.

Sized for the correct age group would be better

Yes, I recommend this

As they have not been worn yet, other than tried on I can’t comment other than to say M&S, why, oh why do you label these as First Period shorts yet sell based on adult sizes?? It was a test and gamble to work out what ‘women’s adult size’ my 9 year old would be, thankfully, I did not humiliate nor embarrass her with my guessed size!

Great shorts, padded not in right place

Yes, I recommend this

Fabulous shorts, very comfortable. The padding I find is too far forward not enough at the back. Perfect for what I want them for though

Poor substitute for others no longer available

No, I don't recommend this

Bought as an alterative to apparently discontinued 2-pack of heavy absorbency shorts, which my daughter found very comfortable. These are significantly shorter and nowhere near as good.

Buy, so good

Originally posted on marksandspencer.ie

I have ordered them again as i find them very confortable and they can hold a lot (i have heavy period where on day 2 i can use around 6 or 7 long maxi pads) and these stay good overnight and on heavy days i change them only twice during the day.

This are first period pants but I use them for lighter days. They are so comfortable and excellent value for money. Wish we had these when I was younger!

Great price and quality

Bought a couple of packs for my daughter. Period pants can be so expensive but these are great value and great quality. Lovely to have a bit of variety of colour too, not just the usual black.
