Ultimate™ only The fabric

Made with TENCEL™ Modal.

TENCEL™ Modal is a cellulosic fibre - made from wood by Lenzing in Austria, not from petrochemicals. It's the fibre Ultimate™ is built on, and it's what you notice in the first ten seconds of wearing a pair.

Soft against skin on the days you least want to think about what you're wearing. And still soft after a hundred washes, which is the harder half.

Wood
Hardwood pulp from certified or controlled sources - FSC® or PEFC.
Fibre
Lenzing spins that pulp into TENCEL™ Modal at its mills in Austria.
Fabric
Knitted into Ultimate™ - the bit of the range you actually feel.
You shouldn't be able to feel your period pants. That's the whole brief for this fabric.
Softness that lastsThe fibre's cross-section and tenacity favour a soft fabric that survives repeated washing and drying.
Moisture regulationThe structure absorbs and releases moisture, supporting a drier microclimate against skin.
Responsible woodSourced from certified or controlled wood sources - FSC® or PEFC.
Lighter productionMade with at least 50% less carbon emissions and water than generic modal, per Lenzing's Higg MSI figures.
Fibre properties and the production comparison above are as published by Lenzing AG (Higg MSI v3.91), measured against generic modal - they are Lenzing's figures for the fibre, not WUKA's figures for the finished pair. WUKA doesn't make the fibre; we choose it. Full composition is printed on every label.

They can be reused for up to 2 years, saving you money in the long-run, too. For the first 40 days after you receive an order we offer a 100% satisfaction guarantee on your first pair of WUKA pants.

Who’s 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. Designed to grow up to.
How does Teen Stretch™ work?
Following the sell-out success of WUKA Stretch™ - the world’s first full brief multi-size period pants, we adapted our innovative Stretch™ Technology for new Teen Stretch™ incorporating a narrower gusset, for a more snug and comfortable fit for younger growing bodies.
