This extra sturdy backpack from Dakine only looks like denim- the body is actually a polyester/nylon composite. What that breaks down to mean is that it has sweet black denim styling, but is WAY sturdier. And on top of that style, all the features stuffed into this bag will have you prepared for anything, like the king of campus that you are. A laptop sleeve and soft sunglasses pocket are neat, convenient features- as is the organizer pocket. But Dakine went a step further, and included an insulated cooler pocket. That means this bag looks good, works great, and can even feed you. Theres just not anything else you could ask for. Built in laptop sleeve. Soft, zippered sunglasses pocket at top. Organizer pocket with padded pouches. Two bungeed mesh bottle pockets on side. Built in insulated cooler pocket. Padded, adjustable H-style straps. 13"W x 20"H, and 9" deep.
