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

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!

Comfy but leaky

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.

Brilliant idea and great quality

Yes, I recommend this

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
