6.5L Cosmo Backpack

This item is no longer available.

A great little backpack for those times when you don't want to take everything with you.

Let's face it, you might not always need to lug 50 pounds of books, electronics and other gear around on your back. However, you also don't want to fill your pockets up with all the little things you need to carry on your daily commute, a quick hike or to the harbor for some water therapy. With a capacity of 6.5 liters, the Cosmo Backpack from Dakine fills that niche between a handbag and a full-size backpack.

You'll find plenty of space for your journal, the latest best-seller, your smartphone or phablet, earphones, keys, writing instruments (there are still some who like to put a pen to paper rather than text), a bottle of water and an energy bar. There are pockets, some mesh and some with zippers as well, and a key clip so everything stays neat, organized and easy to find. There are even some webbing loops on the front to clip items you might want to grab quickly.

All this with a rugged, 600 denier polyester outer fabric in the season's best colors and patterns, a smooth nylon lining and adjustable straps for comfort. And if you were still needing another reason to make this your favorite easy travel companion (not likely), Dakine gives this backpack their limited lifetime warranty against manufacturing defects. Imported.
