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 underwear– 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™ Underwear is 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?
WUKA Teen Stretch™ launches in the UK with a bold ‘Pay Your Age’ campaign, valid from 26 Jan until 28 Feb 2023, meaning instead of the usual RRP of £18, 16-year-olds, for example, will pay £16 per pair for their first three pairs, whilst 12-year-olds will pay £12. This offer will be available exclusively at www.wuka.co.uk
How easy is it to use Teen Stretch™?
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.
What is the changing bag for?
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™ Underwear 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 underwear don’t like it!
Struggling to have the “first period” chat?
The perfect match for Teen Stretch™ Underwear, WUKA changing bags feature two zipped pockets so you can change and store your used underwear in separate compartments. Made from 100% waterproof fabric, the double pocket reusable bag is perfect for storing used WUKA underwear 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.

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.”
