Here is the gear list for my Appalachian Trail journey. It went virtually unchanged during my hike. I got a lighter sleeping bag for the summer after I sweated one too many nights away.
Send me an email and I can send you the spreadsheet itself, Excel formulae and all.
I owe a lot of gratitude to previous thru-hiker Reese, whose trail journal I read while preparing my own trip. He posted this spreadsheet with his gear on it, and I stole the template because it was well-organized and looked nice. I figured the best thing I could do in return would be to put my own spreadsheet up so that other hikers-in-planning can use it as a jumping-off point.
Please leave me a comment if you have questions on anything you find.
