A look at the Tom Bihn ID Messenger Bag
This may come as a total shock to you all, but I am into gadgets. I also like bringing with me every gizmo that I might possibly need when I go out. I’ve got my SwissTool, my iKlear, my zip ties and my FlyLight. My cell phone, my camera, my mouse pad and my iSight. For the last 6 months I’ve been toting around all that, my iBook and quite a bit more in my Willow PK-02: Thoreau Backpack and in those 6 months I have developed some considerable back pain from all that gadgetry.
Inspired to downsize

Out of the blue came the Tom Bihn ID Mid-sized Messenger Bag. I went through a bit of inner conflict as I came to the realization that all the gak I used to carry in my Thoreau simply would not fit in the ID. Don’t misunderstand me: the ID has plenty of room for any normal human being with a healthy outlook on what one should be expected to keep with them at all times. It’s just that, with the Thoreau, I was able to keep all the necessary tools for every eventuality packed and ready, with the ID I am forced to pack only for the anticipated events of the day. An exercise I was greatly in need of actually. About the bag The Tom Bihn ID Bag is a messenger style bag, meaning that it has a single |

Open the front flap to reveal an open-top pouch and organizer for the essential gadgets of the day ahead. On the flap itself is a rather large pocket with a waterproof zipper. The main cargo bay of the ID has snaps for an optional, and highly recommended, Brain Cell laptop sleeve. The Brain Cell is designed to cradle you ‘Book and absorb some of the shock it might encounter on the road. The flat pocket on the back of this bag is the perfect size for documents. |

Tom Bihn has also thought to give the ID a waist strap that keeps the bag in place as you where it while riding or running for a train. Provision has been made to allow for a Cat Eye flasher to be attached to the bag for extra visibility by motorists at night and Tom Bihn has made the ID available in several eye catching colors that will you similar attention during day rides. |

Pros and Cons
I really like the size of the ID and although it won’t hold all my iBook accessories
it is sufficient to hold the ones I’m likely to use in a single outing. It is
also very strong, well constructed and light. Gotta like that.
I really like the waist strap because it gives me an added sense of security
to know that anyone who might try to run by and snatch my ‘Book is gonna have
to take me along with it.
The Brain Cell add-on is a nice touch and keeps you ‘Book safe from your other
items while still leaving it accessible.
On the downside, I wish there were some divisions made in the main cargo area.
The organizer in the front of the bag is great but it would be nice to have
similar features inside that accommodated the larger items I carry. And while
Tom Bihn never specifically marketed this bag to wardrivers, being as this is
the Wardriver Wednesday column I don’t feel that it is totally inappropriate
to mention that the bag is not quite big enough to tote an iBook or PowerBook
and a Pringles
Can Antennaóyou are likely to crush your can if you try.
More info
According to their web site. the Tom
Bihn ID Mid-sized Messenger Bag is available in sizes to fit 12″ and
15″ PowerBooks and and the 12″ iBooks. It evidently is too small for
the 17″ PowerBook and 14″ iBook is uncomfortable positioned between
the 12″ and 15″ sizes.
All things considered, I must say that the Tom
Bihn ID Messenger Bag is my favorite of the multitude of bags I’ve tried.

I was very excited when I found out I was going to get to review the next generation 
Many of the features that impressed me about
The business end of the ID is its laptop compartment which is located under the pocketed flap (unlike the Tom Bihn Super Ego) and provides ample room for a notebook the size of a 15″ MacBook Pro or smaller, some books, maybe a Wacom tablet and even a light jacket.
The back of the ID has an additional open-top pocket that is great for flat items like magazine, books or papers, or anything you want to be able to get at quickly.
One beef I had with the old ID design was the way in which Tom Bihn incorporated support for the Brain Cell. At that time, the Brain Cell attached via metal snaps, which was very handy when you wanted to pop it in and out. But it meant that if you didn’t buy the Brain Cell, you had two snaps inside your messenger bag waiting to scratch the dickens out of your laptop. Well, since then, the Brain Cell has changed and, with it, the way it connects to Tom Bihn’s various bags. Though I highly, highly, highly recommend getting a Brain Cell or some sort of laptop sleeve, if you do decide to forgo that extra line of defense, the ID is much less abrasive to laptops “going commando” in its main compartment since the Annex clips used to attach the Brain Cell are removable.
One new feature of the ID Messenger Bag is something Tom Bihn calls the Q-AM or “Quick-Adjust Messenger” strap. I’m a big believer in giving things names that immediately tell you what they do and why you need them. For this reason, I call this strap the Starbucks Strap. Have you ever driven to Starbucks, realized you couldn’t leave your laptop in the car unattended while you went in and got your over-priced specialty coffee? That meant that you had to bring the bag into the coffee shop, which, is no big deal until you actually get your coffee and you have to customize it over at the cream and sweetener table. Because, as you reach over to get the carafe of half-and-half off the back shelf of the table, your messenger bag slides from behind your back, swings around and smacks your grande decaf half-soy, half-low fat, iced vanilla, double-shot, gingerbread cappuccino off the table and across the room. The Q-AM strap prevents this kind of tragedy. It effectively secures the messenger bag to your back by connecting one more point on the bag to the shoulder strap perpendicularly under your arm. It’s hard to explain, but after you use it, it will be harder to explain why other bags don’t have this feature. I’m told that this will also keep your bag on your back while you ride your bike like one of those guys who deliver documents downtown. Sure… I guess…
