Made for your light flow to medium flow days, but not heavy days.

 

Wuka swimming pants holds up to 2 tampons worth of menstrual flow. It's important to remember they should only be used for a light period and light menstrual flow. On your heavier days you would need to use a tampon or menstrual cup and could wear the period swim pants as a back up.

 

Extender Wear Time Warning

Period swimwear is designed to absorb your menstrual blood while you are swimming and are fabulous to wear for your regular swim, swimming lessons etc. However they are not designed to be your sole source of all-day protection. When you need to wear the costume for an extended period such as a day at the pool, beach or a waterpark you can't wear just the one costume all day without the risk of leaking. Why? The swimsuit will also absorb pool water, and if you've been wearing the costume for an extended time it will also have absorbed blood so when you come back to sit on your sun lounger, beach towel or queue up for a ride there is a real risk that the excess water that drips or is squeezed out as you sit will be tinged red with blood.
So what do you do for all day wear?
I'd recommend you have two costumes so you can change throughout the day. How frequently you need to change costumes will depend on how heavy your flow is and how often you are in the water. This might be every 30 minutes or every 2 hours. When you go to change, wipe yourself clean as much as possible, put on your new costume then rinse the worn costume until the water runs clear. Then dry the used costume in the sun or in a towel until you may need to change the costume again. A dark or black towel to wrap around yourself or sit on when you get out of the pool would be better than a white or lightly coloured towel. You may also consider a menstrual cup or disc for heavier flow days, with the period swimwear providing additional protection against leaks.
