WHY YOU’LL LOVE IT

The Stretch™ Period Boxer gives you full-coverage comfort with built-in period protection. It feels like your favourite loungewear - but works like your go-to period care. No VPL. No leaks. Just soft, secure support that moves with you. Fits 3 body sizes so it adapts as your teen grows.

HOW IT WORKS

The wider, absorbent gusset absorbs 20ml+ of period blood - about 4 tampons' worth or 3 pads. Ideal for heavy flow days, spotting, discharge, or even post-workout sweat. Made from Stretch™ fabric that gently hugs your body - no digging, no riding up.

BEST FOR

Heavy flow days. Lounge days. Sporty days. Perfect for under skirts and jeans. These boxers are breathable, reliable, and built for up to 12 hours of freshness.

GOOD TO KNOW

Wash before first wear. Reusable for up to 2 years, saving around 200 disposables.

Who is Teen Stretch™ for?
Teen Stretch™ is designed for young tweens and teens aged 8 - 16 navigating their first periods. Ideal for the first period or as their bodies grow through puberty.
How does Teen Stretch™ work?
Following the sell-out success of WUKA Stretch™ - the world’s first full brief multi-size period pants – last year, we have adapted our innovative Stretch™ Technology for new Teen Stretch™ incorporating a narrower gusset, for a more snug and comfortable fit for younger growing bodies.
Will Teen Stretch™ save me money?
Raising fast-growing teens can be expensive - keeping up with their constant needs for new clothes, shoes and sports kits doesn’t come cheap! WUKA Teen Stretch™ pants are an affordable, comfy eco-friendly solution designed to last for up to 2 years and fit up to 3 sizes meaning less expense, waste and one less thing to worry about!
Is Shipping included?
Yes! Throughout the launch period (26 Jan - 28 Feb 2023) all orders of Teen Stretch™ will also qualify for free shipping. T&C's apply.
How easy is it to use Teen Stretch™?
Switching to WUKA could not be easier for young adults. No more awkward moments, period emergencies or leaky disasters. Designed to completely replace pads and tampons, WUKA Teen Stretch™ pants can be worn for up to 12 hours so tweens and teens can carry on with school, sports and whatever else they do for fun on their period- with nothing holding them back. Simply wear, machine wash and air dry. Avoid tumble drying- WUKA pants don’t like it!
What is the changing bag for?
The perfect match for Teen Stretch™ pants, WUKA changing bags feature two zipped pockets so you can change and store your used pants in separate compartments. Made from 100% waterproof fabric, the double pocket reusable bag is perfect for storing used WUKA pants and pads until you’re able to hand wash or machine wash them. Available in blue, back, red and even a limited edition leopard print design.
Struggling to have the “first period” chat?
It can be tricky to navigate the first time but don’t worry, WUKA has some fantastic books to help you have those important conversations. Check out the Girls Guide to Growing Up Great by Sophie Elkan - it’s funny and wise and the perfect read for growing girls!

The fit is amazing

“The fit is perfect, and my daughter finds them really comfortable. I was initially concerned they might feel hot or make her sweaty, but she’s assured me that isn’t the case at all.”
