There's no need to choose between style and function with the DaKine Aspen 20L Rucksack. DaKine nails it once again with the perfectly-sized 20 liter Aspen, done up in unique canvas fabrics and with a hooded top flap to keep the elements out. The Aspen 20L fits most 15" laptops and comes with a drawstring closure under the flap to keep everything secure.
