Osprey Packs: Exposure 50 Backpack

Perfectly suited for gear-intensive technical climbs and ski mountaineering trips, the Osprey Exposure 50 backpack comfortably carries loads of 55 to 60 pounds. For a relatively small pack this is a rather amazing feat, accomplished by a lightweight yet exceedingly strong suspension system composed of a tapered HDPE framesheet with a 7001 aluminum alloy tubing perimeter with an 6005 aluminum alloy head cup extension. And to further reduce the weight, Osprey made a series of circular cutouts in the framesheet. Over the top of the framesheet a thermoformed backpanel offers luxurious contact with the climber's back and a heat moldable hipbelt disperses the weight throughout the hips, taking the edge off lengthy load hauls to the base of climbs. Although the Osprey Exposure 50 backpack has a simple top loading design, the innovative features, in addition to the suspension system, are well thought out and all have a practical use. For example, on either side of the main pack bag, just below the floating top pocket, rope tie-ins secure a coiled rope so it rides without shifting back and forth. Other examples include an internal hydration bladder pocket, and a straightjacket compression system that allows shredding alpinist the ability to carry a snowboard on the Osprey Exposure 50 backpack. Of the four packs in the Osprey Exposure series, only the Exposure 50 offers a crampon patch and its also cleverly equipped to carry skis, a snow shovel, wands, pickets, and ice tools. The custom moldable hipbelt even has gear loops for convenient access to climbing hardware.
