Sounds well thought. Get out and go and you will find what you do not need. Just a sugestion Nalgenes are awsome but a bit heavy. I took a plastic gallon milk jug and cut the top off made it about five inches high . This is very lightweight and goes inbottom of pack ontop of sleeping bag. This makes a awsome sink for sponge baths. Lighter than the nalgene wring out washcloth and dry or put in ziplock bag to hit the trail. I also have several alcohol stoves. Anytrip over three days and I would take my little 2.1 oz colman and two fuel canisters. It is just more efficent. Hope this helps. Sounds like you have already discovered what works for you.
Hi Everyone, My first post on here. From Australia and locked into walking the JMT this summer. End of July into August. Really looking forward to walking America's great trail. A little background: 65 years, like lots of you guys been walking them thar hills since I was a boy. Now graduating into the 'lighter' weight category after years of luggin' all sorts of bizarre ex-Army stuff etc. up hill and down dale. I've invested in a Henry Squires Tarptent [ the Squall ], bought an 800gram bag, a titanium stove, carbon fibre sticks, moved over to Merino clothing, and otherwise tried to squelch my 'gear freak' inclination to buy the latest gee-whizz gadgets. Hard to do but my feet will thank me. Great to have a forum for us pre-Boomers and Boomers. Eventually I hope to write a piece on tackling the JMT from an overseas perspective. The logistics, believe me, are horrendous... Best, PeterR
