The big brother of the Ypsilon school backpack is ideal for everyday life in high school. With no complicated adjustments, the lightweight and ergonomic school backpack perfectly fits the anatomy of the teenagers. The Deuter Contact back system with the newly developed Lumbar Pad transfers the weight gently to the shoulders and pelvis even during growth. Even a hip belt is unnecessary due to the good fit. The result: more freedom of movement! The front pocket offers additional space for helmet, ball or jacket - perfect for after school.
