High Absorbency Period Bikini Knickers

Really happy with these knickers. Not bulky, very discreet. I will be purchasing more.

Brilliant! Having read about so many brands online I decided to try M&S when there was a Sparks deal on - what a bargain! For me the fit was true to size and comfortable.

Period knickers are great. However, it's a shame they're in limited colours and patterns.

Definitely size up - I read the reviews and ordered a 12 instead of my usual 10 and they felt snug on the hips. I already have some period pants which I use with tampons on heavy days and on their own on light days, so I bought the heavy absorbency M&S ones to try. I wasn’t expecting them to be perfect for me because Day 1-2 of my period is super heavy (ultra/super plus extra in tampon terms). I tried them on Day 1 and they only leaked because they couldn’t absorb the blood fast enough after I’d been sitting or lying down for a while and then stood up creating a bit of a “flood”. There was still plenty of absorbency left at the front and back. I think they would be completely fine if you normally use super/super plus tampons. I used them on their own from day 3 of my period onwards and there were no leaks. Overall I was impressed. Pink ones washed fine too with no staining.

Pleased with these pants, absorbs well and no smell. Comfortable to wear all day too. My only downside is that these give me a panty line due to being bikini style. I hope M&S will do Brazilian style period pants.

These pants are great! No more worrying about leaking overnight and they actually look really nice and are comfy as well. I have bought more as I was really impressed

Amazng, no leaks, much better than i had imagined.

Comfortable fit. Still working out if safe to use with very heavy period.

My 12yr old daughter can get very insecure about her period protection and ends up layering up to 3 layers including pad. However she has been able manage with just these and her usual cycling style shorts under her school skirt and has lasted all day. They have also helped with night-time leaks

Good fit. Thin gusset considering they're hugh absorbency. So far all seems good, no leaks, dry instantly. Happy with these pants.
