Period Pants

Yes, I recommend this

I bought 2 packs - one for me and one for my daughter. I found the pants to be comfortable and effective. My daughter (age 15) was less keen and said she did not find them suitable for heavy days.

Great Outcome

Yes, I recommend this

These worked very well for me, very pleased. I usually have quite heavy periods for the first few days and it affects my sleep because I have to wake up to change in the middle of the night. However, I tried these and they are very comfortable and worked quite well. I still can’t sleep as long as I’d like to but I can at least sleep for 5 hours before feeling like I need to get up.

Comfy and leak free!

Yes, I recommend this

Comfortable and good absorbency. Better than the ‘super heavy’ underwear. Would definitely recommend these and will purchase more.

Terrible absorbency

No, I don't recommend this

I am so disappointed in these! I bought three packs after reading a review in a newspaper and these came out on top. I do not have a heavy flow and these leaked at a ridiculous rate. I need to find out if I can have a refund. What a waste of money.

Good quality but useless if you want to wear pads

Ok so pants are the usual M&S great quality, BUT assuming you want good absorbancy, you might want to wear pads with this product - the pads don't stick to the lining!!!! fundamental flaw I would have said!!! Also the seam across the back of the gusset stops the fabric stretching so it's uncomfortable and at times visible through trousers. Not their best product.

I thought they would have cotton lining but they do not and the lining irritates me.

Brilliant, look like normal underwear & very soft

Yes, I recommend this

Really please with these. I was looking for period pants that look and feel more like normal underwear. These are very good, much less bulky and love the colours.

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.
