You are only required to carry items from your gear list that you may need prior to reaching your next campsite. A small to medium sized backpack, with a volume capacity of up to 2000 cu in (30 liters), is appropriate. The specific items to carry generally depend on the time to reach camp and trail and weather conditions. Typically, you will have inside your daypack: waterproof gear, extra clothing, water, snacks, gloves, hat, sunglasses, and other small items, such as bug repellent and sun screen. Consult your guide if you are unsure of what you need.
Everything else should be placed into your duffel bag, which the porters will carry. The weight limit of the duffel bag is 15 kgs. The porters will carry the duffel bag from campsite to campsite. Use plastic bags or dry bags to separate and water proof your gear. You will be expected to pack your daypack and duffel bag each morning. Note that it is acceptable to use a backpack instead of a duffel bag. However, since porters bundle the bag with other items and carry the load on their heads, a duffel bag is preferred.
