Comfortable but not enough protection from leaks

No, I don't recommend this

Not great unfortunately. Not nearly enough padding at the rear, so leaked overnight on only a medium flow. Would not recommend for heavy flow or at night.

Weird fit

No, I don't recommend this

Unfortunately it wasn’t up to the mark. Probably my mistake of trying other products first. I am used to Bodyform fit and while the M&S were cheaper, I did not like them at all. The only thing that was alright was the quality of the material. Also, I am quite unhappy from M&S in general because I paid for next day delivery and did the not get the product on time. I then got an email that my delivery cost would be refunded and that never happened so I am just done with the company.

Not for your heaviest day

No, I don't recommend this

Maybe ok for medium flow days but certainly not worthy of the ‘heavy absorbency’ label. When you have been sat or lay for a while and stand up and gravity happens, they are unable to handle the sudden increase/absorb it fast enough and it will spill onto the sides of the pants. I would not recommend.

Great pants

Yes, I recommend this

Great pants. Daughter is pleased. I am glad that adult sizes are available in the cheaper kids range, as she's only just 13 but tall and strong. Washed up well so far, but not been thoroughly tested yet.

Good for medium flow

Very comfortable and well made. Not absorbent enough for really heavy flows and the cover is too short at the back. Still good product for medium flow.

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.

Yes! a comfy pair at last.

Yes, I recommend this

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

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
