FAQ: Heavy Flow Period Pants

Heavy Flow period pants are WUKA’s most popular choice, holding 20 ml for reliable protection on heavier days. Soft, breathable, and reusable, they are perfect for work, school, or long days when you need trusted comfort and security.

What does Heavy Flow absorbency mean?
Heavy Flow absorbency is designed for days when your period is heavier and you need extra protection. These pants lock in leaks and odour while still feeling soft and breathable.
How much can Heavy Flow pants hold compared to other absorbencies?
Heavy Flow pants hold 20 ml or more, around 4 tampons or 3 pads. This sits between Medium Flow (15 ml) and Super Heavy (60 ml), making Heavy the best everyday choice for strong flow days without the thickness of Super Heavy.
Are Heavy Flow styles suitable for overnight wear?
Heavy Flow pants can be worn overnight for many people. For peace of mind on very heavy nights or postpartum bleeding, Super Heavy or Overnight styles offer maximum back coverage and capacity.
What styles are available in Heavy Flow?
Heavy Flow absorbency is available across popular styles such as Midi Brief, High Waist, Bikini, and Boxers. This gives you the flexibility to choose the cut that feels most comfortable and supportive for your body.
How many pairs of Heavy Flow pants should I buy for my cycle?
Most people find 3 to 5 Heavy Flow pairs ideal for the main part of their cycle, then mix with Medium Flow for lighter days or Super Heavy for the heaviest days. Teens and those with longer cycles may want more pairs to reduce laundry time.
What if my size changes due to bloating or body changes?
If your size fluctuates, multi size styles like WUKA Stretch adapt across several sizes and stretch comfortably with your body during bloating or growth.
Are Heavy Flow pants safe and chemical free?
Yes. WUKA period pants are lab tested, REACH compliant, and free from harmful chemicals. Independent testing has shown no silver detected in WUKA pants and none of the PFAS banned by REACH. WUKA does not use antibacterial treatments.
How do I wash and care for Heavy Flow pants, and how long will they last?
Rinse in cold water after use, then machine wash at 30 to 40°C without fabric softener. Air dry only. With proper care each pair lasts up to 2 years, saving over 200 disposables from landfill. For details see the Wash Guide.
