Fabric and performance
Made from recycled polyester/elastane, the Bella Legging is engineered for performance activewear. The elastane delivers 4-way stretch that moves with her body and recovers its shape - no more saggy knees at the end of the school day. The recycled polyester wicks moisture away from the skin, keeping her cool and comfortable through every activity.

Frequently asked questions
The material was top notch! It was stretchy and moved with my teen's body as she rumbles and tumbles without scrunching up in weird places. I love that the designs are age appropriate, classic and clean without any loud matured prints. My kids LOVE wearing them. They even wear it underneath their school uniform to keep them warmer during winter!
My daughter absolutely love her leggings! Great fit, super comfortable. Looks stunning too
