The ultimate Denali pack. For extended winter mountaineering adventures.
Alpinists can now haul their heavy winter gear without adding weight to their load.
Constructed with Spectra fabric that is ten times stronger than steel, and sewn together with a Kevlar combination thread, this pack is one of the lightest, toughest mountaineering packs on the planet. More info, pricing and places to buy Kelty, Vapor 45 Backpack For short ultra light trips of a few days, the Vapor 45 is the toughest, lightest pack around. Kelty sized this first generation of Spectra packs as if they were being stuffed with all the normal junk one takes on a normal trip. Like the Cloud but a little smaller, the Vapor is perfect for long hard alpine climbs of a more mortal length. Completely modular, the Vapor can be as big, or small, as you want it to be.
