The Metanoia is named after an un-repeated route first climbed by the founder of Lowe Alpine, Jeff Lowe. In 1991, after 9 days alone & unsupported on the North face of the Eiger, he completed a visionary new route, which he called Metanoia. This brilliant pack celebrates Jeffs bold & uncompromising style of climbing with its clean & uncluttered design & lightweight, strong & technical construction & is perfect for expedition climbing or extended winter mountaineering trips. To achieve the nirvana of lightweight & strength Lowe have developed a highly tear resistant Tri Shield fabric which is 54% stronger than traditional PU coated fabrics but a lot lighter. This makes up the main body of the sack with heavier duty material covering the main wear areas. The single large compartment is accessed through a traditional lid opening which has a large extending valance to increase the carrying capacity & a webbing top strap to either compress the load or attach ropes & crampons. The whole top lid can be removed to create a stripped down Metanoia for fast final ascents or if you just need to keep the weight to a minimum. Load carrying is taken care of by the Adaptive fit shoulder harness & padded hip belt; Adaptive fit allows for a wide range of body sizes from a fixed harness. The back panel is covered with a water & snow shedding material over moulded padding with ventilation channels & is designed to sit close to your back for security & stability on technical climbs & long approaches. The back system is supported by an internal wire frame which can be removed to reduce weight & there is a removable foam pad for use as a bivvy/seat pad. The padded hip belt distributes the loads for long approaches & can be stripped down to a simple webbing belt to not interfere with your climbing harness; the padded section tucks away into a sleeve on the side of the pack. Your essential winter tools can be carried on the Metanoia using Lowes brilliant Head Locker & Web Catcher systems that quickly & securely attaches ice axes, skis. walking poles & probes etc. Gear loops on either side of the pack take care of climbing gear & twin tape daisy chains down the front provide additional attachment points or storage. Zipped pockets on the lid take care of any bits & bobs that you need quick access to.
