Description of Mountain Hardwear SuperNatural 55 Backpack This clean, zip top design suits overnight trips, hut-to-hut trekking, travel, day hikes, and even technical outings like ski touring and cragging. Fully custom, highly stable body-hugging shape integrates the shaping and support of a FitLock harness directly with a stiff, load bearing back panel. Frame contours to the torso, and internal lift pulls pressure off the shoulders and distributes weight throughout the upper body. A dual density hip belt completes the package, and can be tucked away for lighter loads. "These packs feature a unique, innovative suspension designed to optimize mobility, stability and comfort. It’s unlike any internal frame design out there. We use our exclusive FitLock pad technology to custom shape the whole contact surface of the pack. This ensures optimal fit, while the stiffness of the FitLock system maintains outstanding control over the load. You’ll understand once you try it on." – Erik Hamerschlag, Product Manager Features: Bottom Fabric: 420HD Nylon Usage: Backpacking / Backcountry Body: 210D Cordura® Capacity: 3050.00 in / 55.00 l Frame Type: SuperNatural Suspension with FitLock Harness Mobility Rating: High Weight: 4 lbs, 0 oz / 1825.00 g Supernatural suspension with FitLock harness and backpanel creates a customized, body-hugging shape while preserving a high level of mobility Load stabilizing foam reinforced panels at top and bottom of pack zip access and laminated flap Top loading with foldover closure designed for use with lid pocket removed Sleeping bag compartment with #10 YKK zipper and laminated flap Hypalon daisy chain offers multiple lashing options Flexible compression and accessory straps can be clipped to multiple points or removed entirely Removable top pocket with welded zipper Easy access hydration pocket Dual density foam padded hipbelt provides excellent control, comfort, and load support
