Clothing considerations differ widely from trek to trek.
A short hike up in the middle of August could be undertaken in shorts, T-shirt, a warm pullover, sandshoes and a sun hat; a higher altitude say above 3000m in June, however, would require a far more comprehensive clothing list. One of the most important considerations is the manner in which you trek.
In all mountain areas you should be prepared for inclement weather. On the other hand, excessive clothing takes some of the simple delight out of the trekking and it can also be very expensive. Remember that most of the clothing that you would take on a weekend bushwalk is also suitable for trekking the Himalayan foothills.
During the period in which you will be walking in Himalayan Kingdom, heat will be just as much a consideration as the cold. For the majority of treks you will not be walking in snow, and it is not necessary to equip yourself with double boots and heavy down gear as if you were about to climb Everest. A sturdy pair of boots is always recommended, as is a good wind-and waterproof jacket and a comfortable backpack which is adequate for your needs. An invaluable extra is a sturdy walking stick - useful on muddy trails and for warding off over-friendly shepherd dogs.
If you are travelling exclusively in Himalaya and are not prepared to carry huge quantities of trekking gear around all the time, you can practically equip yourself in Nepal. A local tailor can make up a pair of shorts and comfortable long trousers in an afternoon. Raw wool pullovers, long johns, string vests, gloves, socks, and balaclavas can be purchased in the bazaars.
