In collaboration with Swedish Posture, the PTP POSTURE backpack has a patented crossover design that allows any weight you carry to rest on your sternum, close to your centre of gravity, where you are the strongest.
This design also leaves your shoulders free for movement, making the backpack feel lighter as you carry your daily belongings.
