WHY YOU’LL LOVE IT

WUKA Stretch™ Heavy Flow Pants are the world’s first seamless, multi-size period pants. Designed as a full brief, they flex to fit your body and offer maximum protection without digging in. Figure-flattering and comfortable, they give you confidence through your heaviest days.

HOW IT WORKS

Made with Stretch™ Microfiber Technology, one pair adapts to fit across multiple sizes. The mid gusset provides full coverage, absorbing 20ml+ of period blood - about 4 tampons’ worth or 3 pads. Seamless construction ensures no VPL, while soft, breathable cotton keeps them kind to skin and hypoallergenic.

BEST FOR

Heavy flow days, bloating, postpartum recovery, or changing body sizes. Perfect when you need secure, leak-proof protection that moves with you. Provides up to 12 hours of wear.

GOOD TO KNOW

Reusable for up to 2 years, saving hundreds of disposables. Due to the delicate nature of the fabric, wash in a mesh laundry bag. Avoid heat or chemicals – do not tumble dry or place on a radiator. Air drying is best. Soft, sustainable, and eco-friendly period care.

FAQs: Stretch Seamless Collection

WUKA Stretch pants celebrate every body. One pair stretches to fit up to four sizes, adapting to your unique shape and even during bloating, so you always get a secure, comfortable fit and a more sustainable period.

What is Stretch technology?
In true taboo-breaking WUKA style, Stretch™ features our new patented Stretch™ technology— a meticulously designed suspended gusset is built in to each pair of underwear, engineered to retain its stretch, expand or contract depending on your unique shape. Figure flattering with a completely seamless construction, you’ll find no VPL’s here.
Who are stretch for?
For everyone who wants a more comfy, leakfree period. Our Stretch™ technology means you can wear these period pants no matter how your body shape and size changes. Our custom collections are design with adults, teens and even people with sensitive skin in mind.
I've just had a baby, can I wear WUKA Stretch period pants?
Perfect for new mothers, WUKA Stretch was designed for you- super soft, comfy and designed to adjust to your body as it changes post pregnancy. The seamless design is gentle and sensitive to skin.
How do WUKA Period Pants work?
Layers. Our many layers contribute to making sure you get a long lasting feeling of dryness and security, not having to worry about leakage, smell or infection. Every pair includes a super absorbent gusset which consists of many layers, the middle layers absorb and lock in the blood whilst working with the outer layer to ensure you stay dry through your day to day activities! Period pants look and feel like your regular underwear but they are leak-proof, which means you don't have to wear a pad, a tampon or menstrual cup when you wear them during your period.
How many pairs do I need?
We find that 5-7 pairs is best for most customers considering they last up to 2 years. Check out our savings on bundle cycle sets for 3 to 5 pairs.
Do WUKA pants contain PFA's?
The simple answer is no! WUKA has been committed since day one to not use any harmful chemicals in the production of our products. All of the materials that we use are planet friendly, animal friendly and contain no added chemicals, such as silver or antibacterial treatments, stain-resistant or Perfluoroalkyl and Polyfluoroalkyl substances (PFAs or PFSAs). All WUKA are independently tested by Highstreet Textile Testing Services Ltd (HTTS) who guarantee there is zero trace of PFA's in our products.
How do I care for my WUKA Stretch period pants
Our WUKA Stretch period pants require a cold wash only. If your machine doesn’t have this setting, hand washing is your best alternative. We recommend treating your period pants as delicates. Using our mesh laundry bag will help to protect the fabric and prolong the life of your underwear.

Leak proof but not as comfy as WUKA organics

Only 3* because I've had WUKA organics for years and have loved them. I thought I'd try these. They aren't as stretchy as they say considering they're supposed to fit large too. I am a size 10/12 normally. Today I am bloated and they're uncomfortable 😣 I can feel the restriction on my stomach and very aware of them when I'm not usually with the others. stupidly bought 5 pairs and now I wish I stuck with the organics.

No leaks though, I just loved the original organic period pants, comfy, stretchy and proper cotton. Will be purchasing them again and again
