FAQ: Period Underwear

Your guide to choosing, wearing and caring for WUKA period pants. Find the right absorbency and style, learn how they work, how to wash them at 40°C, and what to expect on heavy and super heavy days.

What are period pants and how do they work?
Period pants look like regular underwear with a built in multi layer gusset that absorbs flow, locks it in and helps control odour. For a quick explainer, see How Period Pants Work.
Which absorbency should I choose for my flow?
Match absorbency to your heaviest part of the cycle. Medium holds around 15 ml for moderate days, Heavy holds 20 ml or more, and Super Heavy holds up to 60 ml for very heavy days and nights. Browse Heavy Flow or Super Heavy to compare.
How do I pick the right size and fit?
Use the size chart to choose your usual size, then fine tune by hip measurement. If your size fluctuates or you want a flexible fit during bloating, try multi size WUKA Stretch. Check the Size Guide for details.
How long can I wear period pants, and are they good overnight?
Aim for up to 12 hours per pair depending on your flow. For sleep or long shifts, choose higher coverage or super heavy styles. Explore the Overnight collection or compare options in Super Heavy.
How many pairs do I need to cover a full cycle?
Most people use 5 to 7 pairs for a full switch, depending on cycle length and laundry routine. If you are starting out, begin with 3 to 5 pairs across different absorbencies and add more once you learn your flow pattern.
How do I wash and dry period pants?
Rinse in cold water after use, then machine wash at 30 to 40°C with similar colours. Skip fabric softener and air dry to protect absorbency. See the full care guide: How to Wash Period Pants.
Are period pants safe and free from added chemicals?
WUKA period underwear is designed to be breathable with no added chemicals. Learn more on the main collection page: Period Underwear. If you have specific sensitivities, review fabrics on each product page and choose what suits your skin best.
Which style should I choose for coverage and comfort?
Choose coverage to match your needs. High Waist gives extra front and back coverage and is popular for heavier days. Midi and Bikini feel minimal while still protective. For maximum capacity, compare a High Waist Super Heavy option here: High Waist Heavy and explore all styles on the collection page: Period Underwear.
