The new Sammies Optilight is a really very good student. Why do we think so? There are simply so many good points in its favor. At just 1,060 g, it is one of the lightest school bags in its class. The Optilight has been awarded DIN 58124 (TÜV Rheinland tested) for its all-round safety package - what an overachiever. The BAG and the AGR certify its 1a ergonomics. The latter has even awarded the Optilight the AGR seal of approval as a particularly back-friendly product.
