For some athletes, light and fast is way of life. For those people, CamelBak has the Highwire 25. This pack weighs less than 2 pounds yet gives you enough cargo capacity for full-on, daylong epics. It's made from lightweight ripstop fabric with a water-resistant coating and it'll haul trekking poles, ice axes, climbing gear — everything you need for an adventure. And thanks to its 100-ounce reservoir, it's versatile enough for day hikes, bike rides and even jaunts through the city. The pack's two compression straps offer incredible stability and its ventilated back panel makes it comfortable for hours on end. Plus, the independent suspension harness takes the weight off your shoulders and the waist belt has cargo pockets so your most needed items are close at hand.
