My old Swissgear day pack has seen better days so I decided to replace it for my upcoming trip to Israel. I thought an anti theft design would be safer, eventhough costly. The Pacsafe Metrosafe 15L backpack was the right size to meet Air Canada’s personal item carry on restrictions (6x13x17 inches). It sells for about $100 on Amazon. I found the same pack for $63 on eBay. Although compact, it easily holds my 11 inch laptop. I think it will be perfect for the trip.
