I have a pretty extensive shopping list, but that's because 1. I'm not used to backpacking where you are walking every day. Normally I get up to a location in one day and stay a week, come down at the end. 2. When you do a trip like that, and you backpack arid regions, you almost never encounter rain and you certainly don't HIKE in it if it does. You hole up in the tent with your favorite person and play cards
So...
1. New pack...I have an old external frame, not good for carrying around for 2 months--REI has a decent 65L Osprey on sale 99 dollars
2. Rain cover for pack
3. Rain gear: jacket, trousers, gaiters, poncho? Not sure which combination will be best
4. New thermals for sleeping and chaffing
5. Maps maps and more maps...books
