Packing List
The following is a list of items that I carry while traveling. Key factors include: carrying the bare minimum, not taking items that will be used only once or twice, and carrying only items you are able to part with if stolen. This list holds for almost any climate in the world, and can be slimmed down if traveling in specific climates. All of these items can be put in a large daypack or a small (day and a half) backpack, with the sleeping bag tied to the outside (or inside if it is small warm weather bag).
Sleeping bag stuff sack containing
sleeping bag (rated to fairly cold)
plastic ground cloth sheet (used when sleeping anywhere to avoid bedbugs etc)
Mosquito bednet and some strings
Sandals (for showers and warm areas)

Clothes:
2 sets of undergarments, socks, t-shirts. Wash one and wear one.
1 pair shorts (also for swimming), 1 decent pants (not jeans), 1 sweatpants,
1 sweatshirt, 1 sweatshirt with hood, 1 raingear/windbreaker
wool socks, stocking cap, thin gloves
Toiletries:
