The asymmetrical front flap of the Zephyr closes with a sturdy 1—1/2" side-release Duraflex Warrior Buckle and has three outside pockets: a horizontal zippered pocket designed to fit DVDs or small electronics; a vertical zippered pocket to provide quick access to a cell phone; and a diagonal, open-top pocket perfect for a plane ticket or any similarly sized accessories you 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 pouch that features 3-D pockets for your PDA, cell phone, and pens, plus a small plastic ring that offers a place to attach either the key snap that will keep track of your keys for you or a TOM BIHN Organizer Pouch (optional; order here). The rest of the pouch offers more open space for you to store your gear.

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 are padded and stiffened by 1/4" (6mm) closed-cell foam to protect contents and maintain sharp looks.

Inside the main compartment, the Zephyr comes with three hard plastic file dividers that make organizing your papers a snap, and keep those important files from getting damaged. The dividers stay put inside the bag, but are easily removed if you don't want them. You can also order extra file dividers for even greater organization.

Also in the main compartment, you will find clips for the optional Brain Cell hard-sided laptop case, so you can turn the Zephyr into a sophisticated and highly protective laptop briefcase. The Brain Cell is available in nine different sizes and provides the ultimate in laptop protection with soft, thick foam padding, hard, corrugated plastic walls, and a suspension system. We recommend using our Laptop Bag Fit Guide to determine which size of Brain Cell is best for your laptop.

The back of the Zephyr features a "roll-aboard" slot on the back that allows you to safely stack the Zephyr on top of roll-aboard luggage. The slot zips shut at the bottom so it can be used as a pocket when you're not using it to fit on a roll-aboard, plus there are two small pockets on either side of the slot for a cell-phone or pens.

Did we mention the handles yet? They are amazingly comfortable — constructed of Ballistic nylon rolled around high-quality, 0.5" thick Poron® foam; they lie naturally together at the top of the bag, so there's no fishing around for your grip. Of course, you can always add the Absolute Shoulder Strap when the load gets too heavy. The Absolute Shoulder Strap, which combines a soft, durable neoprene pad with comfortable stretch backing, has a unique patented internal control-stretch system that has given it a well-earned reputation as the best shoulder strap available.

The Zephyr is made out of 1050 denier ballistic nylon and 500 denier Cordura®, and features #10 YKK® Uretech® splash-proof zippers for the main compartment and exterior pockets.

A larger version of the Zephyr — the Empire Builder — is also available.
