How big should our backpack be?

We recommend using three backpacks:

–      A 75-100L backpack or a larger one for transporting all your belongings in the altitude camps

–      A waterproof duffel bag big enough to fit the large backpack for transporting your personal items from the park entrance until base camp and return.

–      A 35L or similar size daypack where you will carry your water, lunch, passport, sunblock, and the clothes you will wear during the day up to the base camp, on the acclimatization treks, and also for the summit day. This 3rd backpack is optional, since you may also use your big 75L backpack instead.

All these are recommendations; please take in mind some climbers have their preferences.
