Activewear for Girls

For Girls Who Love To Move

We support tween and teen girls to live active lives and feel comfortable and supported doing it. However she loves to move, our four-way stretch fabric will move with her, our no-rub seams will prevent friction and our sweat-wicking properties will keep her cool and dry. And when she’s enjoying down time, Lava Tribe activewear gives her the chance to express her sporty style with fresh designs, bold prints and on-trend colours.

Our range is based on the basic principle that no matter what a girl sets out to achieve, if she feels comfortable and confident, she’s more than half way there.
