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’d recommend wearing them at home for one day, so you can get to know your flow. This will help you to decide the best level of absorbency for you (light or high) and how frequently to change your knickers. Patent No. GB2588289 & GB2586813
