On trek, all of the group equipment and most of your personal gear is carried by porters or pack animals (Yak/Horse) according to the route. Each trip member will carry in their daypack the following items: a snack, water bottle(s) or hydration system like camelback; raingear and any extra clothing you might need for the day according to weather conditions (e.g., sweatshirt, fleece jacket, ear band or hat, gloves, etc.); your camera and film; sunscreen, lip balm, sun hat, etc.; and any other personal items you want to have handy during the day's hike of 6-7 hours.
