Athletik Tween Promise
Designed specifically for girls aged 8–14, Athletik Tween focuses on comfort, coverage and confidence during the in-between years, clothing that supports movement and independence without asking her to grow up too fast.

Measure the body (not the garment).
If between sizes, we recommend sizing up for comfort.
How do I choose the right size?
We've aligned our sizing with Australian standards, but every girl grows differently, especially in the in-between years. We recommend choosing based on how she likes to feel: snug and supported or a little more relaxed.
What if I'm unsure about sizing?
You're not alone — most mums are navigating this stage too. If you're between sizes or unsure, we suggest sizing up for a longer-lasting fit and extra comfort.
Will it fit as she grows?
Our pieces are designed with flexibility, stretch, and movement in mind, so they adapt to her body and keep her comfortable as she grows and moves.
What if the size isn't right?
We've got you. We offer a 30-day return policy, so if something doesn't feel quite right, you can exchange or return it with ease.
Is it really risk-free?
Yes — completely. No stress, no pressure. Just finding the fit that helps her feel confident, comfortable, and completely herself.
What's in the set
- Sienna Cropped Hoodie — cotton French Terry, light warmth without the bulk
- Ava Joggers — straight leg, cut for tween proportions
Both in matching Portello, in the size you select once.
Why these two
This is the set she'll live in. Cool mornings before sport, the drive home after training, weekends at home — it covers the parts of the day that aren't really an occasion.
Both pieces are 100% cotton French Terry: soft on the outside, gently looped inside. Warm enough for an early start, breathable enough that she won't overheat by mid-morning. That in-between weather is exactly what it's made for.
