Period Underwear – Black

Meet Period Underwear, knickers with built-in period protection in three flows: Light, Medium and Heavy, so you can pick what suits your day instead of reaching for a one-size-fits-all pad. This is our first product in this category, launched as a trial, and we genuinely want your feedback to help shape where we take it next. They're built on our bestselling Full Brief Knickers, with four specialist layers doing the work instead of our usual two. They'll feel a touch more padded than our regular knickers, simply because the protection is doing its job, but they stay soft, flexible and comfortable to wear all day. It's been over two years in development, wearer-tested by real people during real periods across all three flows, and fit tested across our full, inclusive 0 to 34 range, because period protection that only fits some bodies isn't protection at all. Why You'll Love Them 🖤 Classic black period underwear, discreet enough for every day. 💧 Three flows to choose from: Light (20ml), Medium (40ml) or Heavy (60ml). 🩲 Wear on their own, just like ordinary knickers, with absorbency built in. 🛡️ Four specialist layers work together to wick moisture away, absorb it, block leaks and stay breathable. 🤗 Familiar full-coverage fit, based on our bestselling Full Brief Knickers. 🌈 Inclusively sized 0 to 34. ♻️ Reusable and washable. Wear, wash, wear again. 🧪 Over two years in development, wearer-tested during real periods and made with OEKO-TEX® standard certified fabrics that are tested free from PFAS.
