Brilliant idea

Bought for my grand daughter and she thinks they are great. Much easier for her to use than pads.

Always covered

Yes, I recommend this

I bought these for my Granddaughter, she can always have a spare pair of pants at school if needed. I thought the pants and bags were a really good idea.

Disappointed

No, I don't recommend this

They didn't work at all. I had high hopes. Bought them as back up to help with heavy periods leaks but they didn't hold. Leaked out the sides even with only a small amount

Misleading absorbency

Yes, I recommend this

Overall, I do like these knickers. They work well and feel comfortable. I was very skeptical about period pants but after trying and realizing how good they are in comparison to pads, I got some more. Two stars down as they are not heavy absorbency, only medium at most. On heavy (not even super heavy) days they last 2-3 hours. That's a lot of pants to go through just in one day. Despite that, I'm really pleased and glad I tried these.

Not what expected

Bought these for a relative. Size was a 12 but I’m told a 10 would have fit better as they stretch and become baggy throughout the day. Also being a period knicker, the ‘pads’ didn’t stay in place the whole day, so said she wouldn’t recommend.

Decent price but not most comfortable

No, I don't recommend this

They’re a good price compared to other brands. However, has that microfibre feel and I went for a larger size for comfort but the waist elastic was still tight, I imagine to ‘leak proof’, but it makes them uncomfortable especially overnight. It’s a shame as I liked the idea.

Cost effective & good for the planet

Yes, I recommend this

Bought for those oops moments and I’m certain they will pay for themselves several times over with the money I have saved on liners! M&S have added more designs and colours recently so I have purchased quite a few; they are also good for the planet with so much less waste. They are comfortable and of good quality, they wash very well and I’m very happy with them 😊
