Not for me

Originally posted on marksandspencer.com (UK)

Not for me. Bought these after reading some reviews about using them for slight leaks. Found that when they were even slightly moist they were uncomfortable to wear.

Didn’t love it

No, I don't recommend this

I wanted to try these shorts as they are not my usual style for heavier period days thinking they were very fitted but the material wasn’t thick enough and the shirts sat lower than I like. May just be my style versus the shorts not being good.

Comfortable but not enough protection from leaks

Originally posted on marksandspencer.com (UK)

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

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

Originally posted on marksandspencer.com (UK)

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. 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

Originally posted on marksandspencer.com (UK)

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.

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.

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

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

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

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.
