How to choose equipment to prepare for a self-help tour in Tibet during the summer vacation? Hiking bags, sleeping bags and so on.

About 60L, 45L may not be enough, because it takes half of 45 to change shoes and sleeping bags! Look at Ward's, or Salova's. It is best not to buy domestic mountaineering bags. The carrying systems of CROSS and ACME are basically no use! Page's is good, too, but I heard that the new one is not as strong as the old one! The most important thing of mountaineering bag is to carry the system, so buy a brand that does better in this respect!
