This may sound stupid but is a problem we often face. Clients bringing up so much clothing and books that you would not even bother reading all. Excess clothing is unnecessary and can be done without. A pair of thermos, a pair of t-shirts, shorts, a few pairs of socks and a nice warm sleeping bag would be enough! (A down jacket if you are in the middle of winter). As for shoes, it is best to bring hiking boots. As long as they are comfortable doesn’t matter what brand name it’s got.
