My husband and I purchased two of these backpacks for a trip to Burma and used them again this year for a three week trip to Africa. No other luggage except a small bag each. They are lightweight and sturdy and can hold enough clothing and toiletries and even a jacket with no problem. We were able to carry them onto the airplane and avoid having to check luggage. The outside pockets are convenient for separating items. My only problem was the top pocket which has netting instead of cloth. The netting tears easily so you cannot put much in the top pocket. Other than that we are very happy with them.
