Pacsafe CourierSafe 100 Messenger Bag - 2007 BCS

Well, where there's a will, there's a way. Just be smart about it, don't leave it out of your sight, especially if you have valuables inside. That way, when you see someone with a wirecutter coming towards your bag, do some karate-chop on the crooks.

With all of the new products coming into the warehouse right now, I imagine it'd take Backcountry's in-house photo studio a while to get some more detailed shots of the bag. Also, the manufacturer doesn't seem to provide any detailed shots either.The handle on this bag looks perfectly sized to hook around a rolling carry-on bag, but your mileage may vary.While photos are cool and all, it's better to see and handle the product for yourself. With Backcountry's amazingly generous return policy, I'd recommend ordering the bag, seeing how it would work with your carry-on, and if it doesn't work just return it. No hassles, no worries, it's easy.

There is no luggage sleeve on the back. The closest thing to being able to attach it to a roll on is the handle or the shoulder strap. If you go onto the PacSafe website or even youtube, you'll see a video demonstration of every bag PacSafe sells (inluding this one). All of the videos show the inside and outside of the bag. I belive they do sell a messenger bag from their "Business" line that does what you're asking.
