Definitely not 'Heavy Absorbency'!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Required a couple of pads inside the pants, which defeats the object of the pants. They were fine for the lighter days (not great, but fine), but really no good for the heavy days.

Bought to reduce single use plastic, so much more comfortable than pads. Easily washed and fabric soft to touch.

Pretty as well as functional. Great when exercising. Might need two pairs on if trampolining!

Not for period. It leaks even in light period. Waste of money, so dissatisfied

I have used these for a couple of years now and they are such a great, sustainable alternative to usual period products. I feel confident wearing them.

Love them. Have had them previously. Made mistake of ordering pink lace ones too, same size and style but as with my separate review, those are awful. Saggy baggy round the back/bum as they don’t have elastic on the join from gusset. Very disappointed with them hope I get a response.

Comfy, absorbent, discreet do the job well. I sized up so did feel a bit bulky compared to normal underwear but pleased with them. Also used overnight and slept well.
