FAQ: School Set – Stretch

Stress-free school-day kit with Teen Stretch™ Heavy period pants and a waterproof changing bag; teen-fit, breathable and leak-proof for up to 12 hours.

What’s included in the school set?
Teen Stretch™ Heavy period pants and a waterproof two-pocket changing bag. The fabric is soft, breathable and designed without itchy labels for all-day comfort.
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 in two directions to adapt to changing shape for a secure, comfy fit.
How absorbent are the pants and are they OK for a full school day?
Heavy Flow absorbs 20ml+ (about 4 tampons or 3 pads) and offers up to 12 hours of protection. Ideal for lessons, PE and after-school; change sooner if they start to feel wet, as everyone’s flow is different.
How does the changing bag help during school and activities?
Use one pocket for a clean spare and the other for used pants after a quick rinse. It keeps bags organised and makes changing simple during breaks, clubs or trips.
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?
With proper care, the pants are reusable for up to 2 years. Many families find 5–7 pairs cover a full cycle; the set is a solid start and you can add more pairs as needed.
