We recommend you take a pair of hard wearing cotton based trousers which will be more comfortable on hot, crowded buses and a lighterweight polyester based pair which are great for trekking and activities as they dry so quickly if wet. Ensure you can wear a pair of thermals underneath if you know you are going into cooler climates.
You will probably only be taking a couple of pairs of trousers (3 at a stretch) so you really do have to like them!
