Say goodbye to discomfort and hello to confidence with Primark’s period pants collection — the reliable underwear for menses that looks and feels like your favourite pair of knickers. Whether you’re after light support for spotting days or full protection for heavy-flow nights, our period underwear is designed to suit everybody, flow, and lifestyle. Each style features advanced multi-layer gusset technology to help lock in moisture and prevent leaks. Depending on the design, our period knickers hold between 2 to 6 tampons’ worth of flow — giving you long-lasting coverage when you need it most. The full-coverage and extended gusset options offer peace of mind for overnight wear, while the soft, stretch fabrics move with your body for all-day comfort. Expect thoughtful details in every pair — like tag-free finishes, flat seams to reduce irritation, and stretchy waistbands that sit comfortably whether you’re relaxing or on the move. Our collection includes a variety of styles: period thongs for light-flow days, high-waisted full briefs that offer gentle support during cramps to mid-rise bikini styles and seamless options that stay invisible under leggings and great for everyday wear. There’s a fit to suit your flow and your outfit. We also have teen styles and starter sets perfect for first-period kits or teens wanting a fuss-free solution. Available in a range of colours and cuts, they blend effortlessly into your lingerie drawer — just like regular panties. All our menstruation underpants are washable, reusable and designed for repeated wear, offering a budget-friendly alternative to pads and tampons without compromising on comfort. Whether you're travelling, heading to work, or relaxing at home, this collection gives you reliable support with no compromise on style or performance. With multiple absorbency levels, flattering designs and long-wear comfort, discover your style below and stay protected every day of your cycle. Pair with any of our jeans for women or leggings for everyday comfort.
