Shirt and Sweaters: Woollen shirts and thick sweaters; these are essential during the winter season (December to February). Thick sweaters can be purchased in Kathmandu. A lightweight long sleeved t-shirt is suitable for avoiding sunburn.
Trousers: A pair of trousers; Jeans are not suitable to wear on treks. Cheap, loose, cotton pants are available in Kathmandu. Heavyweight trousers are useful higher up in the mountains in the morning and at night. Windproof or waterproof trousers are required on all treks going above 10.0 ft.
Tracksuit: A tracksuit is comfortable to wear in camp and in the tent. You want to add at least two pairs of loose fitting long shorts or skirts.
Underclothes: Thermal underwear is the best for sleeping during the winter.
Sun Hat, SunCream/Block & Lip Salve: Choose a high factor sun cream (Factor 20 or stronger) to protect your skin against the sun at high altitude. A combination sunblock/lip salve is ideal for facial protection. A sunhat having a wide brim should be used which covers your face and neck. A woollen hat is a must during winter.
Glove/ Sandal/ Socks: A pair of gloves; Leather with lining and woollen are best, 1 pair of sandals to wear in the cities and in the camp and about 4 pairs of thin and 4 pairs of thick woollen socks are required accordingly.
Sleeping Bag: As you do not carry sleeping bags yourself, this can be either synthetic or down but it is a must for all 4 seasons. As most treks pass through a variety of climatic conditions, a long zip is a good idea. A cotton/fleece liner helps keep your sleeping bag clean. Good sleeping bags are expensive but can be rented easily in Kathmandu (Only for treks starting and finishing there.)
Personal First Aid Kit: You should have your own supply of plasters, aspirin, diarrhoea tablets and also a comprehensive blister kit. (Please do not give medicines to local people without consulting the trek leader.)
