Lightweight rucksacks

Yeah, maybe it would do all that...

But I wouldn't want to look like a dork carrying it on my back...

Or, you could use it for your "emergency abandon all ships" backpack by the door...

Only works for laptops up to 15.6" size. My Deuter rucksack happily swallows an 18.4" model in a padded compartment.

Lightweight rucksacks: Considerably heavier when items placed inside.

I'll get one!

It's just the right size to hold my 300 yen bottle of mayonnaise, cardboard to build a temporary shelter, spoons to dig me out of earthquakes, plastic portable toilet and chainsaw.

Hang on.

I think I've forgotten something.

iPad Mini fits in your cargo pocket. Who needs this? Don't carry around a laptop.

Cool thing is that it can also double as a そり, if you need to evacuate from a snowy mountain.
