Columbia Star Range Square Backpack PU8673 Black This is the slim version of the three Star Range Square Backpacks. It has three main compartments and can hold quite a bit for its 16-liter capacity. I think it's designed to minimize wasted space. It's also very light. I've developed severe frozen shoulder and can no longer comfortably wear a backpack. I've used it for about 3 months, but it's still in great condition, so I'm putting it up for sale. ■ Size: Approximately W28 x H42 x D9 (cm) *Based on manufacturer's specifications ■ Material: 840D TM OX (100% nylon) ■ Weight: Approximately 610g ■ Capacity: Approximately 16L ■ Pockets: (Outer) x 5 (with inner pockets) (Inner) x 3
