The Poler Rucksack backpack is one of Poler's classic best sellers. The added side zip pouches increase carry capacity and give the pack a unique look. The external access laptop compartment lets you retrieve your work with ease and without fear of rearranging your meticulously crammed main compartment. Speaking of cramming, the cinch top design lets you push the limits of what this bag was meant to carry, so go ahead, bring a change of clothes. You have room.
