I'm going to add my 2 cents on Lands End or LL Bean. My husband had a Lands End laptop backpack that traveled the world literally, with the laptop in it. Many trips to China, Hong Kong, Japan and India on top of daily use. I washed it several times in a both a regular washing machine (in a stackable apartment machine) and a front loader in cold water, air dried. It lasted forever! He still has it and uses it as a back up, it was an older model that didn't have all the extra pockets for things like cords, mouse etc and he upgraded to a more modern version. My son's preschool backpack is/was also Lands End it's been on vacation and used for various other things on top of two day a week preschool for two years, it still looks brand new and my younger son is now going to use it since we're upgrading to a Kindergarten size this fall for the older one. I went with LL Bean on the new one because there were a lot of complaints about the zipper being hard to access and or getting caught on the fabric on the Lands End version. No matter what you won't spend a fortune (easily under $100) and the investment will be worth it.
