Deuter Speed Lite 20 Backpack

With external straps to lash skis, a snowboard, or an ice axe, as well as mesh pockets to stash a water bottle or raincoat, the 20-liter Deuter Speed lite is capable of a lot more than its slight profile suggests. And it's also extremely versatile - the hydration bladder sleeve is the right width to keep your 13-inch laptop secure, and if you slip out the Delrin rod that forms the pack's frame, the 1.2 pound Speedlite can cram into any corner of a larger pack, making it the ultimate travel or summit pack.
