The Babbily Eco-Fit explorer leggings that grow with your child have been specially developed for active, adventurous children to get through every adventure effortlessly - without chafing at the knees. While there are trousers with a robust or grow-along function, Babbily's explorer leggings are the first leggings to combine comfort, durability and grow-along function. One pair of leggings replaces at least 3-4 conventional pairs, reduces textile waste and conserves environmental resources. Comfortable for children, practical for parents and good for the environment.
