Comfy but don’t do their job.

No, I don't recommend this

These are soft and comfortable to wear but not suitable for nighttime use or heavy flow. Not only did I leak out of the top of the padded section when worn at night but in the day, the padded section itself became wet and blooded on the outside after a few hours of wear. For a full brief advertised for heavy flow I would expect the padding to be longer and better.

Don't hesitate just buy them!

Yes, I recommend this

I am a heavy bleeder so i was cautious when choosing this product. Definitely should have got them sooner. They are comfortable, true to size and as advertised high absorbency. Amazing price point too considering some are £20 each pair! Have recommended to anyone that will listen.

Weirdly big

No, I don't recommend this

Bought these in my usual size and they are like nappies. Would only wear at night! They sit very high on the waist which i would love if they fit.

Yes, I recommend this

Bought these for light middle of the night accidents when one does not get to the loo on time. They do the job well.

Not for me

No, I don't recommend this

Not for me. I found them big and cumbersome. I did purchase the lace high leg and they are truly wonderful. From memory the were £5 more maybe that’s the difference

Leaked through in 2 hours

No, I don't recommend this

Leaked completely through after a couple of hours wear. I was expecting these to be great but sadly it leaked completely through the gusset after not long wearing at all. These clearly can’t handle a heavy period despite being labelled heavy absorbency.

Not as good as they were

No, I don't recommend this

I don't think the quality is as good as it used to be. Too many seams and lables now. Nowhere near as comfortable. They are okay period pants with regard to absorbency etc.

Love

Yes, I recommend this

So comfy, TTS with room for bloat. I wouldn’t wear them without a liner on heavy flow days but great for lighter days and extra protection overnight

Good value

Yes, I recommend this

These are good value compared to other brands. They are extremely generous in size- which makes them comfy if you are bloated. They are quite bulky but good for price

Real piece of mind

Yes, I recommend this

These knickers have been a god send for my mum who has endometrial cancer bleeding. These knickers make sure her clothes and bedding are protected. I prefer the pink/burgundy colour but these are no longer available.
