Period knicker convert

Yes, I recommend this

I’d never used period knickers before and wasn’t sure whether to trust them, but these had such good reviews, which were right. They are so comfortable and I even wore them to bed without any trouble. I got a heavy absorbency to hopefully safeguard against any issues and that was great. Truly converted and telling every woman I know to get some! Such good value from M&S too and easy to wash without fabric conditioner. Happy to have plastic-free periods going forward!

Brilliant, reliable period knickers!

Yes, I recommend this

I bought these recently for my daughter. The knickers are great. They are reliable, comfy and look good too. I bought size 4 for my slim 11 year old daughter and they fit perfectly. In fact, I bought 3 sets!

Absolute game changer

Yes, I recommend this

I’ve been skiing and was so anxious about heavy flow and no quick access to the toilets. These knickers are soft, comfortable and very discrete way to remove this stress. Highly recommend!
