How to Measure Your Hip SizeHow to measure your body

WUKA TIP: No tape measure? 
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length.

WHY YOU’LL LOVE IT

A classic bikini shape that feels just like regular swimwear, with built-in period protection. Designed with an ultra-absorbent liner, these briefs give you the freedom to swim, surf, or paddle without worrying about leaks.

HOW IT WORKS

Each pair holds up to 10ml of menstrual flow - about 2 tampons or 1 pad - making them ideal for light period days. Made with a waterproof outer, chlorine-resistant recycled nylon, and UV50+ protection, they’re durable, breathable, and quick-drying.

BEST FOR

Perfect under wetsuits, mixed and matched with your favourite bikini tops, or worn under shorts for watersports.

GOOD TO KNOW

Wash before first wear. Each pair is reusable for up to 2 years, saving around 200 disposables from landfill. Eco-friendly, mix-and-match ready, and made for real life in and out of the water.

Free UK shipping using Royal Mail 48 (untracked) on 1-2 items - EXCLUDES SALE PERIODS. Tracked 48 on orders with 3 or more items (swimsuits/leggings/sports shorts/hot water bottle will use Tracked 48 as standard). 1st Class Signed For available for £4.50 Get Free International Shipping on orders above £75.

HANDWASH: After use, rinse with cold water.

MACHINE WASH: Pop your WUKA with similar, dark coloured garments and wash at 30 to 40 degrees. Don't use fabric conditioner.
We suggest that Perform Collection and Re-purpose Collection styles should be washed cold. We also recommend washing any WUKAs with mesh or lace in a wash bag. This will help prolong the life and the strength of the mesh.

LINE DRY: Air dry your WUKA Period Pants outside on the line or indoors on an airer. Don't tumble dry it.

For the first 40 days after you receive an order we offer a 100% satisfaction guarantee on your first pair of WUKA pants, this allows you to try them hassle free. If they don’t fit then you are welcome to exchange for a different size or get a full refund.

Our Period underwear and sportswear feature a super soft outer that absorbs quickly and feels dry. 2. The super absorbent inner locks in blood. 3. Leak-proof layer keeps you secure and odour-free.
SUPER ABSORBANT

Our swimsuit features a built-in ultra thin, absorbent gusset to prevent leaking when swimming.

FAQ: Leak-Proof Period Swimwear

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

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.
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.
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!
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.
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.
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!
Two styles. The high waist style is available for adults whilst the classic bikini brief is available for adults and teens.
Adult Sizes range from XS- 4XL in both the bikini and high waist swim briefs. Teens Swim Bikini Briefs are available in sizes 2XS - L.
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.
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.
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.
Yes. Our period swimwear is seawater and chlorine-resistant which helps to prevent fading and keeps your swimwear long-lasting.
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.
