I'm 61, in very good shape, 6' tall and 175 lbs. I've section hiked about 1000 miles of the AT over 10 years and am planning a thru hike attempt in 2013. I want to replace some of my gear. With cost not being a problem, what would you suggest for a 1. pack 2. warm sleeping bag 3. two man tent, all that are ultra light weight and will get me to Maine. I'd like to be 12-18 lbs. without food and water. Thanks for any help you can offer.
