Good absorbency and really comfy. There's not much of a VPL like with other period pants.

Works well decent absorbency

Yes, I recommend this

Good absorbency for light to medium flow, not had heavy yet. I’d like the main pant to be in natural materials

Comfy but not entirely leakproof

No, I don't recommend this

Comfortable to wear but I did have leakage at the sides. They didn’t stand up to their ‘heavy absorbency’ label

Worth the money

Yes, I recommend this

Super soft and comfortable. Almost feels like seamless too. I feel confident when wearing this on non period days too for managing small leeks. I only hope they have these in normal waist length as well instead of low or high.

Amazing environmental period pants!

Yes, I recommend this

Bought these for my daughter, she says they are brilliant, work perfectly. I am so pleased that there is now an environmental way of managing periods that doesn't need disposable pads or tampons.

Comfortable.

Yes, I recommend this

Got these for playing sport as cant stand micement of disposible pads. Very comfortable for that purpose. Will yake some getting used to as the black pad makes sense but means you cant really see how used it is.

Not great

No, I don't recommend this

There is a bit of a line between the fabric and the main part of the pant which you can feel when wearing them
