Lightweight rucksacks

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

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

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.

Lightweight rucksacks: Considerably heavier when items placed inside.

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

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

Yeah, maybe it would do all that...

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