Medium flow period pants FAQs
Liberty medium-flow period pants absorb up to 25ml per pair. They are designed for medium-to-light flow, with built-in absorbent protection for everyday wear. Choose your preferred seamless, ribbed or soft bamboo-viscose style.
Yes. You can wear Liberty medium-flow period pants on their own when their absorbency suits your flow. If you are trying period pants for the first time, check regularly to learn when you need to change.
Wear time depends on your flow, activity and comfort. 25ml capacity does not guarantee a fixed number of hours. Change whenever the pants feel wet, uncomfortable or close to capacity, and carry a spare pair when needed.
All three styles offer up to 25ml absorbency per pair: Seamless High Waist: a smooth nylon/elastane finish for a discreet silhouette under everyday clothes. Ribbed High Waist: a textured ribbed nylon/elastane finish with flexible stretch. Soft High Waist: made with 95% viscose from bamboo and 5% elastane for a soft fabric feel. Choose according to your preferred fabric, finish and fit.
Consider Seamless High Waist in an available nude shade close to your skin tone. Its smooth finish can help reduce visible underwear lines. Visibility will also depend on the thickness, colour and fit of your outer clothing.
Yes, if their capacity is suitable for your overnight flow. For heavier nights or when you need greater absorbency, explore Liberty’s heavy and ultra-heavy period pants. Change into a fresh pair before bed and change again when needed.
Yes, provided the size and absorbency suit their needs. Choose by waist and hip measurements rather than age alone. A spare pair and a wet bag can make changing at school or while out more convenient.
Measure around your natural waist and the fullest part of your hips, then compare both measurements with the size guide for your chosen product. The pants should fit securely around the waist and legs without digging in. Follow the product’s guidance if you are between sizes.
Rinse in cold water after use until the water runs clear, then machine wash at 30°C with similar colours. Avoid fabric softener and bleach. Follow the garment’s care label for drying.
Drying instructions differ by style. Seamless and Ribbed High Waist should be line dried. The Soft High Waist product instructions also allow tumble drying; follow its garment care label for the appropriate setting. For a mixed pack, check each pair separately.
