I would like a laptop bag, messenger style, that has room for a laptop
(dimensions: 14.5 inches wide, 11.5 inches deep, and 2.25 inches high)
a power pack (dimensions: 4 inches wide, 1.75 inches deep, and 7.5
inches high), as well as some room for files, pens etc, and a pda. The
entire bag must lined with a durable material that will withstand
regular use, and block any kind of electronic signals from entering or
leaving the bag (including wifi/bluetooth/cell phone signals, and the
output from the battery). Externally the bag must be able to withstand
rain and a harsh Canadian winter (-40c weather), so nothing that's
going to freeze and crack, but something that will take a hammering
and survive. It will not be immersed in water, but will have to
survive a freezing-rain shower every week or so.

It's hugely important that the bag is shielded from the aforementioned
electronic signals, and also well padded to prevent damage to hard
disks/laptops within). Messenger style bag required with a black
colour preferred.

Dimensions do not have to be exact, but will need to fit in all of
those components as a base :D

Thanks for the comment, I have secured my laptop to paranoid levels,
and I'm not so much worried about people hacking in via wifi (they
wouldn't be able to), but I'd like it to be shielded so that if some
random guy decided to start scanning around for laptop power emissions
etc, my laptop would be off the grid. I have seen some bags that have
a small pouch with the material I desire, but it will only fit a cell
phone...... But for the life of me I can't find the link I originally
viewed it on

Gee, I'd like one, too.
If you disconnect the battery, that will usually make signals
unavailable to detectors. I know with Cingular, if the battery is in
the phone, they can track it. This would apply to certain computers
that are wifi enabled and/or wirelessly connected. Usually, mobile war
driving is done with some additional, other types of equipment. There
is plenty of software available to mask,encrypt,or otherwise scramble
any signals emmanating from a computer.

Hi,

  I do understand your concern.  Seems like you need it for some covert
operation.  If you need magnetic shielding, search for mu-metal.
A thick copper/aluminum plate with proper sized holes(essentially a faraday
cage) should take care of high frequency em signals from (smps switching supply), 
processor clock dividers and the VGA chip, apart from hdd controller and
other associated chips.  Also know that your laptop power pack is going
to generate plenty of heat(which means it is easy to identify with a
sensitive infrared detector), so you need perfect insulation for that
as well, but with good thermal conductivity to reduce/disperse any hot spots.
