Does the job & useful

Yes, I recommend this

Not as comfortable as the older versions because the edging on the legs & waist is not so soft & flexible

Excellent pants

Yes, I recommend this

If you care about the environment and your health then buy these period pants. My daughter has been wearing different brands for a few years but rates these as the best. They are very good quality and also very well priced.

Comfortable confidence

Yes, I recommend this

I bought these because I am sick of wearing pads for stress incontinence as they seem to make condition worse and make me uncomfortable. These pants are super comfortable, easy to clean and probably better for the environment. I wish I'd had these pants when peri menopause caused frequent heavy bleeding. Now I'm through that stage my bladder is causing me grief, but these pants have helped enormously. They are a little expensive, but so worth it.

Amazing product! Will buy again and again!

Yes, I recommend this

These work amazingly. I have several pairs to last me throughout my cycle! They don’t leak, the don’t smell (which is what I was worried about) and they don’t feel like you are wearing period underwear, and you can’t see them. I go for the big pants, that is more for comfort after two babies, but I’m sure the other are amazing also!!

Good product but could do with more colour choice

Yes, I recommend this

These are comfortable. It would be good if there were more colour choices though than black with a leopard print.

Happy days

Yes, I recommend this

I am incontinent & bought these pants to help me get through the day without having to change all my under clothes. With the help of pads I have achieved this, they have made my life bearable and I can now wander further afield. I have since ordered further pants. Happy days

life enhancing pants!

Yes, I recommend this

I First starting wearing these pants a couple of years ago to replace panty liners. I am really pleased with them as they seem to work very well for me. I am passed menopause now and wear them for occasional leaks which unfortunately can happen anytime anywhere. The pants are a great fit and not at all bulky. I have tried different brands but these m&s ones are by far the best fit, quality and price I have found. I have recommended them to several of my friends.

Brilliant

My daughter has a very heavy flow and she says these are the best period pants that I’ve bought for her, ever. They are not bulky to wear, and keep her dry and confident. Also, they dry really quickly after washing, unlike some of the competitors. Will be replacing all her other ones with these.

Disappointed

No, I don't recommend this

I found the gusset size very good however I wouldn’t say they’re for heavy absorbency and the odour isn’t particularly pleasant. Sadly I wouldn’t buy again

They work! They really work

Yes, I recommend this

After washing, the knickers don't feel bulky at all, and they do exactly what it says on the tin - heavy absorbency.

I do not recommend if you have super heavy periods

No, I don't recommend this

Sadly disappointed- super heavy really isn’t how I would describe them. They couldn’t even cope with 4 hours of wear. Fine for a back up with pads but definitely not even close to adequate. I leaked everywhere- not good enough.
