Decades of design and build experience resulted in this briefcase. You’ll hand it down to the next generation.

The Empire Builder is the result of three years of product development and 30 years of bag-building experience. It is uniquely styled, superbly functional, and built to endure years of abuse.

The asymmetrical front flap of the Empire Builder closes with a strong 2" side-release buckle and has three pockets: a horizontal zippered pocket to fit power supplies or small electronics; a vertical zippered pocket designed to store an iPhone for quick access; and a diagonal, open-top pocket for a plane ticket or any similarly sized items you might need quick access to.

Under the front flap, there is a large, zippered front pocket that extends almost the length of the bag, and behind that pocket, a large open-top pouch that has two organizational pockets for notebooks or small electronics, three pen pockets, and a business card pocket, plus an O-ring to which the included 8" Key Strap is attached. Key Straps are useful for keeping track of your keys (many folks leave their keys attached to the Key Strap) and can also be used to clip a pocket watch or Swiss Army knife to the bag. (Additional and extended-length Black and Color Key Straps can be purchased separately.)

The main compartment unzips low on the sides, exposing a "bellows" that allows access to the depths of the bag. The front, back, bottom, and sides of the Empire Builder are padded and stiffened by 1/4" (6 mm) closed-cell foam to protect its contents and maintain its sharp looks. Inside the main compartment are three hard plastic file dividers (included with the bag) that make organizing your papers a snap. They also help to keep those important papers from getting damaged by the other contents in the main compartment. The dividers stay put inside the bag but are easily removed if you don't want them. You can order Extra File Dividers for even greater organization.

Also in the main compartment are two unobtrusive webbing loops (that we call "rail loops") to which you can secure the optional Cache (available in sizes specifically for every Apple laptop and iPad; PC users, click here for our Laptop Bag Fit Guide). When you add the Cache, the Empire Builder becomes a "checkpoint-friendly" laptop briefcase. Here's how it works: on the back (or bottom, depending how you look at it) of the Cache are two parallel "rails" of 1" wide lightweight nylon webbing which extend from the top to the bottom. Included (and already attached for your convenience) when the Cache is ordered with the Empire Builder are two Gatekeeper Rail Clips: unclip the side that isn't clipped to the Cache, slip it through the webbing loops in the Empire Builder middle compartment, and flip it shut. Slip the Cache inside the Empire Builder, and pull it back out: you'll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop from the Empire Builder entirely while it is still encased in the protective Cache. Doing this at the airport security checkpoint means the X-ray machines (and TSA personnel) will have a clear, unobstructed view of your laptop — allowing you to keep your laptop in the Cache and the whole affair securely held together as one unit. (We think that's much better than having to remove your laptop and dump it in one of those buckets.) Many of us will appreciate this functionality on a daily basis as well: the rail system can be a convenient and quick way to remove one's laptop from the bag.

The back of the Empire Builder features an open-top pocket for magazines or newspapers. It also has a slot that allows you to stack the bag on top of rolling luggage — slip the handle of the rolling luggage through the slot on the Empire Builder. The slot zips shut at the bottom so it can be used as a pocket when you're not using it to fit the bag on rolling luggage.

Did we mention the handles yet? They are amazingly comfortable — constructed of U.S. made, 1050 denier, high tenacity ballistic nylon rolled around high quality, 1/2" thick PORON® foam; they lie naturally together at the top of the bag, so there's no fishing around for your grip. The Empire Builder can also be carried across-body or over the shoulder with the optional Absolute Shoulder Strap. The Absolute Shoulder Strap, which combines a soft, durable neoprene pad with comfortable stretch backing, has a unique internal control-stretch system that has given it a well-earned reputation as the best shoulder strap available. We say it makes bags feel 50% lighter, which might sound like a bunch of marketing nonsense, except it's actually true.

The Empire Builder is made of our custom, U.S. made, high tenacity 1050 denier ballistic nylon and is lined with U.S. made 420 denier High-Tenacity Classic Parapack nylon. It features #10 YKK Aquaguard® water-repellent zippers for the main compartment and exterior pockets. The front pocket under the flap has a #8 YKK coil zipper.

your bag already has great built-in organization. that said, you may want to add these optional organizational accessories to further organize and protect what you carry.


The Cache is a protective laptop or tablet sleeve that's available in many sizes to fit a wide variety of devices. It clips securely inside of the Empire Builder.

Freudian Slip

Adds eleven pockets of organization to the Empire Builder — four pen/pencil pockets, two flat zippered pockets, two large open top pockets for file folders, two wallet or phone sized pockets and one credit card sized pocket.

Shoulder Straps

The Absolute Shoulder Strap has a unique, patented, internal control-stretch system, making it the ideal shoulder strap for those who carry hefty loads or simply want the most comfortable strap available.

You can expect your TOM BIHN bag to give you years of hard service. Our bags are guaranteed to be free from defects in materials and workmanship for the life of the bag. That means if something goes wrong and it's our fault, we'll fix it at no charge.

Defects in materials or workmanship are uncommon and are most often evident while your bag is still new. Keep in mind that daypacks and briefcases are often subject to serious wear in everyday use. We often see TOM BIHN bags that are still solid and in use after five, ten, fifteen, even twenty or twenty-five years, with minor repairs needed here or there. But remember: only true love lasts forever.
