A. You need to have enough gear to be warm and comfortable but without overloading. Usually you will experience warm days and cold nights depending on altitude and the time of year. Most treks to around 3000 m. are really quite comfortable especially in springtime. Please refer to my web site for a suggested list of items to bring or e-mail me for our equipment list. It is worth remembering you can buy or rent a lot of what you will need in Kathmandu before your trek at very reasonable prices, I can also provide our own back pack to you for rental. Footwear is best purchased at home before your arrival to ensure they are comfortable and worn in.
