Size and Fit

We have designed BackTpack models in sizes to pre-schoolers through adults, because it is important to train good posture and healthy carrying habits from a young age. Carrying is a natural and necessary part of life. A BackTpack will promote optimum spinal health and natural body movement while you carry, no matter your age.
