Western Mountaineering - UltraLite

Western Mountaineering's UltraLite is a versatile 3-season bag that weighs less than some people's backpacking whiskey rations. If your summer bike tour or backpacking trip is going to take you through different climates, the UltraLite is the way to go; its continuous baffles allow you to shift the down on top of you in cold temps, or underneath you when the weather warms up. With a 59 inch shoulder girth and 5 inches of high-lofting 850+ down, this efficient bag is good to 20° F. The full down collar helps to seal in heat around your neck without adding excess bulk, and the full length draft tube seals in heat along the zipper. The total weight of this very compressible package is under 2 lbs, so you can take the UltraLite anywhere.
Like all of Western Mountaineering's bags, the UltraLite is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.

I would like to buy a Western mountaineering, ultralite which is cheaper in the US than in Norway where I live. I am going to a conference next week in New Orelans and wonder if there will be any problem having it delivered to my hotel address. I see on your web page that items ship within 24 hours. How long do you reckon until delivery in New Orleans? I leave back to Norway on saturday Feb 4th and need to be certain that I get it in sufficient time ahead of my departure.
