Lovely soft material, true to size, comfortable, pulls up to great level so not digging into my stomach. I found them suitable when on my period.

Great set of period pants for my teenage daughter, she wears with a pad but feels more confident at school in these than normal pants

I bought these again for my teenage daughter as they make her periods easy to manage as well as being environment friendly. I would recommend, I wish these had been around when I was a teenager.

Comfy and great quality

Originally posted on marksandspencer.com (UK)

Really comfy and good quality. I'm an adult and these work totally fine for us too - not just for teens! I use with a tampon the first few days just as a backup to avoid leaks (although honestly most people with regular flow could probably use just the pants), then just on their own on lighter days. Feels just like wearing regular underwear, not bulky at all. No idea why but these don't seem to accumulate a smell like pads do - on lighter days I wore the same pair all day and they were totally odourless.

These are the only period pants my teen will use! She doesn’t need to worry through the school day as they are heavy absorbency.

Just ok

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Bought as daughters first period pants but she wasn’t impressed with the amount of padding/absorption. Not as substantial as other period pant brands. K for light flow I think, but better worn with sanitary pad for heavy days which kind of defeats the point!

Simply a life saver for my 12 year old. No complains, it does what it says it will do. Easy to wash, easy to change, it looks good. I cannot stress enough how much that made life easy. I wish these products were around when I first got my Period. A true life changer & money & confidence saver!

Comfy but leaky

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Pros: - really comfortable and well fitting - feel dry even when worn for hours Cons: - leaks round the sides before the rest of the pad has filled - badly stained after just one use It's such a shame. I would have bought more if not for the leaking.

I brought these period pants as I was told they are good for the first time child starting their periods, less embarrassing than sanitary pads , I researched this and they have great views for young girls and hopefully no embarrassing leaks , I have heard they are great for bladder moments

Bought for my daughter who has learning difficulties. These are an enormous help to her as she doesn’t always remember to use a pad when on her period.

Looks like a good product, but it's so thick - feels like walking with diapers.
