I purchased this as carry on back for budget airline. It's light and roomy to hold Tablet, personal items, walking sandals, jacket, waterproof , make up and sandwiches. Trial packing shows that they should fit. Sternum and waist strap are useful to spread the load and keep pack on my narrow shoulders. A zip up inside pocket would be an advantage -I will have to sew one inside myself. Sternum strap is too short and too low at highest adjustment for anyone with 36+ bust. I will have to add some extra webbing. All in all a good pack for carry on, or low level walking but I wouldn't use it when trekking up a mountain.
