Trekking gears should be quality one if you are going to climb peak, but if you are trekking below 4000 meters than normal trekking equipments will be enough such as slepping bags, down jackets, pair of sucks, pair of pant, warm hat, gloves, sun glass, water bottle, medicine, walking pools, water proof bags and jackets, rain coat etc. If you are hiring a porter you better to bring or buy here when you are in Kathmandu a duffel bag and 10 liter day bag for you to carry your important things.
