I bought this Backpack to take to Indonesia. I used it as both carry on & checked luggage with Aprox 6-9kg. surprising how much I got into it. It’s bigger than it looks at first. The pack was compact, lightweight, fit comfortably on my back, was easy to access the compartments as it works like a suitcase, can use as a bag or pack. An optional shoulder strap would be nice but suited my needs as it was. I didn’t really use the 2 smaller top compartments much however if you had an iPad etc it would fit nice and snug. I Look forward to more trips with my pack. No regrets with my purchase - great price, very good quality product & quick delivery.
