These pants are designed for heavy periods but I find them fabulous for light incontinence. They are very comfy, look like normal underwear and do the job brilliantly!

Good quality pants

These pants do the job of stopping leaks for older women as well. Like the clever marketing as Confidence pants.

Comfy but don’t do their job.

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.

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.

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. 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

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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.

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
