Backpacking Gear Packing List and Analysis Spreadsheet. This is a link to an Excel Spreadsheet that I got from a fellow Assistant Scoutmaster and modified to suit my needs. It is filled with actual data for a scout going to Philmont. In the first set of columns, enter in the gear you have and what it weighs (use a postage scale). In the columns to the right, enter any lower weight alternative gear you are considering for each item. The sheet will give you a running tally of what your pack and clothing weighs, how much weight you would save through using the alternatives and how much it will cost you to buy the alternatives. For example, substituting Platypus bottles for Nalgene bottles saves a lot of weight for a relatively modest cost, as does trading a Z-fold Thermarest for a traditional inflatable Thermarest.
