FAQ: Leak-Proof Period Swimwear

WUKA period swimwear is designed to absorb periods and little leaks whilst in or out of the water.

How does waterproof swimwear actually work?
WUKA swimwear features a built in absorbent gusset made of three unique layers. The breathable top layer is designed to feel soft and comfortable to the touch as it sits closest to to your skin. The second layer is highly-absorbent and moisture wicking, helping to absorb up to 3 tampons worth of blood. Lastly the final or outer fabric is aquaphobic meaning it is water repellent which prevents water from entering the gusset and protects against leaks. While it is safe to swim in period swimwear on your periods, we suggest using a menstrual cup or other products as backup on your heavy flow days.
Can I wear them on heavy flow days?
WUKA period swimwear is recommended for use on light to medium flow days. If you are using them to swim for long periods of time, they are best for lighter days. If however, you’re spending the day lounging by the pool with only the occasional light swim then they can also be worn on medium flow days. We do not recommend them for heavy flow days.
Can I wear the swim briefs whilst using other products?
Yes of course! For added protection on heavier flow days, we recommend wearing the swimsuit alongside a menstrual cup, disc or tampon- the more sustainable and plastic free the better!
What Material is your swimsuit made of?
As a certified B Corp that places sustainability at the heart of our brand mission, our WUKA swimwear collection is made from recycled nylon so no virgin plastic are used to make the fabric. Remember each WUKA replaces 200 disposables going to landfill.
What does UV50 protection mean?
Also known as Ultraviolet Protection Factor (UPF), UV protection indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin. For example, our swimwear collection is made using UV50+ protection fabric which blocks 98% of the sun's rays and allows 2% (1/50th) to penetrate, thus reducing your exposure risk to harmful rays significantly.
How do I wash them?
Rinse them in cold water before washing to remove any excess blood. Wash them in the washing machine on a delicate program at 30°C maximum. Do not use any fabric softener or detergents. Air dry and never use a tumble dryer!
What sizes are the swim shorts available in?
Sizes range from XS- 2XL.
How do I know what size of Teen Swim Bikini to buy for my child?
2XS:4-6, XS:6-8, S:8-10, M:10-12. These are just for recommendation. We know all kids grow at different rates, so the best way to get the right size is measure the widest part at the hip and see our size chart to get the right size. You can always ask our customer support if you need help. Anther way to get the size right is by matching with high-street brands, if your teen wears size 4-6 opt for 2XS, if they wear 6-8 go for size XS, If they wear 8-10, go for small size.
Can I wear WUKA swim even when I am not on my period?
Your WUKA is one period swim collection is perfect for wearing in the water- whether it's by the pool, the beach or under a wetsuit. Whether you are on you period or not, they are great to use. The leakproof gusset is built into all of our period swimwear to be discreet and undetectable, so they look and feel just like regular swimwear.
Can I return my period swimwear?
Yes! All of our swim bottoms and one-pieces are eligible for a return or exchange within 30 days of delivery, as long as the original sanitary strip and tags are attached.
Is the swimwear chlorine-safe?
Yes. Our period swimwear is seawater and chlorine-resistant which helps to prevent fading and keeps your swimwear long-lasting.
I am scared that I might leak in the pool
If you have a fear of using WUKA in the pool, we suggest you use them only on your light flow day, till you gain confidence.

Good purchase, but would like larger size options and more style options

Very happy with purchase as water tight when wearing, just wish there was more size options as they only went up to XL, and a XXL would have been a better fit as the shorts rid up almost instantly due to being on the small side.

Would like more options for swim shorts other than the 2 options given, including some longer short options, as I am very self conscious in swim wear and like to cover up between mid-thigh to knee length for highest confidence levels.

Very Small.

I’m a size 12-14 on the bottom half (10 on the top). Bought the large as couldn’t believe u would need the largest size they do. They are very tight, especially around the legs. For a size 14, I feel I would need XL really. Shame they don’t accommodate for larger ladies. Haven’t tested the quality of the period side of things, as have them a miss and think I will return for a bigger size.
