Servicing leisurely snowshoes as well as frantic first-chair missions, our lightest, fastest adventure pack is now adapted to your winter lifestyle. We've removed the outer mesh from the original Mobex and replaced it with Omni-Shield(R)-armed riptstop, ensuring that the foul weather and your gear stay on opposite sides of the pack. A three-liter Hydrapak(TM) hydration pack and its hose are kept freeze-free with Omni-Heat(R) thermal reflective technology, and there's also a stash pocket for a handwarmer near the mouthpiece to keep things flowing on those sub-zero days. True to the Mobex legacy, this pack's Flex Frame(TM) features a comfortable-wearing network of flexible poles that provide featherweight structure and spring back to life when crushed. The unique clamshell opening allows full access to the main compartment for easy loading and unloading.
