This Nike SB Sportswear PRM Backpack (style FD7544-291) shares the Honeydew/Black/White colourway with plenty of room to spare, at 53 x 33 x 18cm and 26 litres of capacity.
Multiple zip pockets keep smaller essentials in order, and the padded back panel with adjustable straps makes it easy to wear for a full day out. Big enough for a 15-inch laptop plus your skate gear.
