FAQ: WUKA First Period Pack - Stretch

Confidence-boosting first-period set with Teen Stretch™ Heavy pants, a two-pocket wet bag and a positive body book; teen-fit, breathable and made for real life.

How does the Teen Stretch™ fit work for growing bodies?
The Teen Stretch™ design fits across three sizes with a teen-specific mid gusset. The fabric stretches bi-directionally to adapt to changing shape for a secure, comfy fit.
How absorbent are the pants and are they OK for school, sport or overnight?
Heavy Flow absorbs 20ml+ (about 4 tampons or 3 pads) and offers up to 12 hours of protection. Great for lessons, sports and sleep—change sooner if they start to feel wet, as everyone’s flow is different.
What does the two-pocket wet bag do and how do we use it?
Use one pocket for a clean spare and the other for used pants after a quick rinse. It keeps school bags organised and makes changes easy at clubs, sleepovers or on the go.
How do we wash and care for everything?
Wash before first wear. After use, rinse in cold water until it runs clear, then machine wash at 40°C without fabric conditioner. Air dry inside out; do not tumble dry or soak for long periods.
How long will the pants last and how many pairs are recommended?
Reusable for up to 2 years with the right care. Many families find 5–7 pairs cover a full cycle; the kit is a solid start and you can add more pairs as needed.
