WHY THEY'LL LOVE IT

The easy way to try period boxers for school. Two pairs of WUKA Teen Stretch™ Period Boxer Shorts for the heaviest days, with full coverage that feels like favourite loungewear. No bathroom panic between lessons and no worrying about leaks or smells. A brilliant first step into period pants.

WHAT'S INSIDE

Two pairs of WUKA Teen Stretch™ Period Boxer Shorts in Heavy Flow, Navy, plus a wetbag to keep a clean spare and a worn pair separate on the go.

HOW IT WORKS

The wider gusset absorbs 20ml of period blood, around 4 tampons' worth, with up to 12 hours of wear. Stretch™ fabric flexes to fit across 3 sizes, so the boxers grow with your child instead of being outgrown, with no digging and no riding up. The seamless fit feels just like regular underwear. Wear, wash and repeat: every pair is reusable for up to 2 years.

BEST FOR

First periods, heavy days, sport, and wearing under skirts and jeans. Two pairs cover one full school day and night, with a quick evening wash ready for the next.

Will 2 pairs be enough?

Two pairs give one full school day plus a night of cover, with each Heavy Flow pair lasting all day for all but the heaviest periods. A quick rinse and overnight dry keeps them going. It is the easiest way to try period pants, and it is sensory friendly with no more mid-lesson dashes.

What is the wetbag for?

The wetbag keeps a clean spare and a worn pair separate in her school bag, so she can change after PE or on a heavier day with nothing on show.

Are they good value?

Yes. Each pair is reusable for up to 2 years, so there is no monthly restock and it works out cheaper than disposables over time. Better for your pocket and the planet.

How do we wash the pants?

Rinse in cold water after wear, then machine wash at 30 degrees. Skip the fabric softener, it stops the pants absorbing as well as they should, and leave them to air dry.
