Size Guide

Think small, that's the rule.

Choose the size appropriate to your needs and body length to get maximum benefit from the ergonomic design, and avoid the temptation to overfill it. Making use of the intelligent pocketing will keep you organised and help balance the weight around the bag.

Remember, the key reasons the Healthy Back BagĀ® works are its body-hugging shape and lack of rigid elements in its construction. It is designed to fit your form and complement your natural balance.
Putting large items inside, like an A4 folder or a chunky laptop, means some of the bag’s functionality may be lost.
