Welcome to SK Athletics — the official sports club of the Silly Koalas

Built for kids who love to play hard, try everything, cheer on their teammates, and have a little too much fun along the way.

Featuring Boomer, the energetic ringleader of Silly Koala, this varsity inspired design brings together the look of a classic athletic club crest with Boomer’s signature silliness. Of course, he couldn’t pick just one sport, so he showed up ready for all of them.

The SK Athletics collection celebrates energy, teamwork, confidence, and the simple joy of getting in the game. With its bold collegiate styling, EST. 2026 club mark, and “Play Hard • Play Together • Have Fun” motto, it’s designed to feel like authentic club apparel kids can proudly make their own.

Perfect for school, practice, game days, weekends, and anywhere the next game happens to break out.

Welcome to the club.

Our suppliers provide these measurements. Note that there could be a slight variation in product dimensions by up to 2 inches (5 cm).

A useful tip is to measure an item you own at home and compare it to these size specifications.

A Length

To measure the length, start at the top of the garment next to the collar (high point shoulder) and extend the measuring tape down to the bottom edge of the item.

B Width

For the width, begin at the seam right below one sleeve and extend the measuring tape across to the seam below the opposite sleeve.

C Sleeve length

Begin measuring the sleeve length at the top of the shoulder seam, then pull the tape down to the end of the sleeve hem.
