Ideal for heavy flow days, these period briefs offer secure protection and comfort. Marks & Spencer's heavy absorbency full briefs feature a three-layer gusset with anti-odour technology. As a trusted UK brand, they are made with responsibly sourced cotton and modal.
Trust in these highly absorbent cotton-modal blend knickers from M&S Confidence range to protect you from leaks. Made in a full brief design for extra coverage, with added stretch for comfort.
Three-layer gusset draws moisture away from the body, with an anti-odour middle layer. StayNew technology ensures longer-lasting colour and finish. Made with responsibly sourced Tencel modal.
We only ever use responsibly sourced cotton for M&S clothes.
When making the swap to period knickers, we recommend wearing them at home for one day to get to know your flow. This helps decide the best absorbency level and change frequency.
