In the latest issue of Backpacker Magazine are 33 tips for lightening your load. One I have pointed out before, but it is worth mentioning again: don’t leave behind items that can make your trip comfortable and/or satisfying. Example:

I have three sleeping pads: 14 ounces, 20 0unces and 36 ounces. Two are self inflatables: a 3/4th length and full-length. They are fairly comfortable, but the third one, while bigger  is not only much more comfortable, but warmer because it provided incredible insulation against the cold ground. That allows me to carry a lighter sleeping bag. About the “satisfying” part of my comment: a fresh apple for lunch or cookies can give your trip and your attitude a big boost.

Be light. Be safe. Be one with the pack.
