Each piece is designed to work together: and independently. Mix, match, layer. Built for the way tween girls actually live.
Soft, breathable and designed for real movement. The Ivy Long Sleeve is the everyday top she'll reach for first: whether it's sport, school or just hanging out.
The legging that stays in place, provides reliable coverage and moves naturally with her throughout school, sport and daily life. No constant adjusting. Just confidence.
Not kids' clothes. Not adult clothes. Activewear built specifically for girls aged 8-14: the years that matter most.
No see-through fabric. No riding up. No constant adjusting. Every piece is tested for the bending, stretching and sitting that tween life demands.
Not scaled-down adult sizing. Athletik Tween pieces are patterned specifically for growing girls aged 8-14, so the fit is right from the first wear.
Clean, classic designs without loud prints or grown-up cuts. Clothes she'll want to wear — and clothes you'll feel good about buying.

“My daughter absolutely loves her leggings! Great fit, super comfortable. Looks stunning too — she wore them to school the very next day.”
“The material is top notch! It moves with her body without scrunching up in weird places. I love that the designs are age-appropriate — not trying to be grown-up.”
“She even wears it underneath her school uniform to keep warm in winter! The long sleeve is perfect for layering. Finally a brand that gets tween sizing right.”
“No more fighting about what to wear to training. She puts this on without being asked. No see-through, no riding up. Worth every cent.”
I created Athletik Tween while watching my daughters move out of kids clothing but not feel ready for teen fashion. Everything we found was either too young or too grown-up, and I realised how much responsibility parents were carrying when choosing what felt appropriate.
So every piece is designed to be comfortable, covered, and easy to wear: clothing that lets them be active and confident without drawing attention or rushing them into a stage they're not ready for.
If you've ever stood in a fitting room unsure what was right, this brand is made to make that decision easier.
All Athletik Tween pieces are true to size. When in between sizes, size up for a more relaxed fit.
