The roll-top opening of the Grounds backpack serves both as a way to adjust the volume and to improve the bag's resistance to rain showers. As a unique feature, Picture Organic has made it easy to repurpose the backpack: if you manage to wear out a part or want a change, you can transform the bag into three separate items: a detachable laptop sleeve, a pencil case, and a waist bag. Instructions for this operation are printed on the inside of the backpack. - Laptop compartment for up to a 15" laptop - Durable outer fabric with TPE coating - Small accessory pocket at the front - Carry handle - Two side pockets with space for items like a water bottle and bike lock - Key clip - Structure and materials protect against rain showers, but for prolonged rain, it is advisable to use a separate rain cover In addition to the TPE coating, the outer fabric has a water-repellent treatment that does not contain PFC compounds.
