Backpack w/ pass-thru slot
 

I'm not sure if the product I'm looking for is like looking for a needle in a haystack, but it's worth a shot:

What I'm looking for is a laptop backpack that has a pass-through slot on the back allowing me to attach it to the handle of my rolling suitcase. To help matters farther (or complicate them more, depending how you look at it), it has to be available in/to Canada and not cost an arm and a leg (ie: <$100). Something along the lines of this bag but in backpack form:

I know MEC has a series of backpacks that are exactly what I am looking for, but I'm not too fond of their construction, nor of the fact I have to turn the backpack sideways to put it on the suitcase.

May also be some more on their site.

If you can't find something, look for a backpack with cinch straps on the top, you can put a strap on those to attach to the handle. I know for example many northface bags have them.

Like the dark grey strap in this one

It's not the best solution, but with the right sized strap or bungee cord works great

I have an older model of one like this:

that I like a lot. Not only does it slide over the handle of my larger bag, it clamshells open so your laptop is in a scanner friendly compartment. Have only had to take my laptop out once, and that was for a very thorough secondary screening in Frankfurt. My only complaint is that there is no water bottle holder.

Thanks for all the suggestions everyone! Now the fun part of finding some of these around town begins. Hah.

I have this one and am very happy with it! Agreed on the water bottle holder though.

I simply pull middles of straps across forming "8" and slide the handle through both openings. Works great.

I have this one and it works great. Nice professional look too.

Backpack with trolley pass through
 

If you haven't bought anything yet-check out

everki.com. Their packs are fantastic. Extremely well made. Not cheap but worth every penny.

Be creative
 

Find a backpack that you like and go to a shoe repair shop to have them sew a sleeve on the back of the backpack. This might be an option for you.

Just realized this thread is from 2011
 

I responded to this thread then realized it was from 2011.....oops.;)

Samsonite have a few of those in their range, they call it a 'smart sleeve'. I have the small Cityvibe in black and really like it.

Anyone have a suggestion for a backpack with a pass-thru slot that looks nice?
I would like to use it for my laptop as well as clothes for 2-3 days for short trips. Ideally it would have some pockets on the outside to make passing through security easier.
It should have a laptop compartment, but I don't like the way most laptop backpacks look. I'd prefer a backpack that doesn't really look like you have a laptop inside.

I.e. I can't stand this design:

But I think this looks ok:

This is quite nice, too (but I think it lacks the pass-thru slot):

Any other suggestions?
I would actually be willing to trade a little bit of functionality for looks. :D
