When you hit the trail, you're probably more worried about the day's goal, some solitude, and the beauty of the mountains, so let the CamelBak Fourteener 24 Hydration Backpack take care of your hydration needs. Weighing in at a little over two pounds and with 1,465cu in of extra storage space, the Fourteener specializes in hydration and maximizes your storage convenience to boot. Because full day hikes require much more than just water, CamelBak fitted the Fourteener with multiple, easily accessible pockets for your sunglasses, extra water, hiking gear, and tools. When not fully stocked with goodies, this pack shrinks, by means of four compression straps, to reduce extra bulk on the trail. The included three liter Antidote reservoir has been perfected over the years by the folks over at CamelBak to deliver slosh free, easy hydration with just a quarter turn of the valve.
