Inside the Horizontal Brain Cell, your laptop hangs suspended, cradled in a sling of 8mm thick soft foam padding inside a 4mm hard corrugated plastic shell that protects from the front, back, and bottom.

Below the padded sling, fixed to the bottom of the corrugated plastic shell, is a 12mm thick strip of memory foam (manufactured to our specifications in U.S.A.) The memory foam acts as an extra layer of cushion as well as an effective shock absorber. The sides of the Horizontal Brain Cell are protected by dense cross-linked closed-cell polyethylene foam.

The Brain Cell is designed to clip securely inside of our Empire Builder and Zephyr briefcases, Brain Bag and Smart Alec backpacks, Western Flyer travel briefcase, or Super Ego, Ego, and ID messenger bags, turning them into protective laptop bags.

For use on its own, the Brain Cell features an open-top, snap-closing front pocket of heavy-weight stretch mesh to accommodate your files, power supply, and mouse. The Brain Cell also features strong webbing handles and "D" rings to accept a shoulder strap. Each of the "D" ring shouler strap attachment points is sewn with six rows of stitching. You can add your own shoulder strap to the Brain Cell, or choose between our Absolute, Terra Grip or the Simple shoulder straps.

Note that in order to take full advantage of the Horizontal Brain Cell's suspension system, it must be carried in the horizontal, or "landscape" format. The laptop protection that the Brain Cell provides is compromised if you use the Horizontal Brain Cell vertically. If you require a protective laptop case to use in a vertical or "portrait" format, see our Vertical Brain Cell.

We build the Brain Cell in 11 different sizes to fit virtually every laptop on the market. To find out which size fits your laptop, use our Laptop Bag Fit Guide. Quick hint for Mac users: the Brain Cell is available in Size 1 for the 17" MacBook Pro, Size 4X for the 15.4" MacBook Pro, Size 6 for the 13" MacBook, and Size 6X for the MacBook Air.
