    Vertical Brain Cell

    A corrugated plastic shell, suspension system, soft foam padding and memory foam work together to protect your laptop.

    The Vertical Brain Cell, like the Horizontal Brain Cell, provides superior hard-sided protection for your laptop. The construction offers the toughest protection you can get for your laptop in a case that is still light and minimalist. Your laptop will be protected from every angle.

    Inside the Vertical Brain Cell, your laptop hangs suspended, cradled in a sling of 10 mm (3/8") thick, soft foam padding inside a 4 mm thick, 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 12 mm thick strip of memory foam (manufactured to our specifications in the U.S.A.). This memory foam acts as an extra layer of cushion as well as an effective shock absorber. The sides of the Vertical Brain Cell are protected by 6 mm (1/4") of dense cross-linked closed-cell polyethylene foam. The case closes on the top, like a cereal box, with two padded flaps that seal with Aplix®strips (like Velcro®, only longer-lasting).

    The Vertical Brain Cell is designed specifically for use inside two of our backpacks — the Smart Alec and the Brain Bag, which come with removable clips that secure the Vertical Brain Cell in place. If you already havea favorite backpack, chances are the Vertical Brain Cell will fit inside it. Be sure to view our Laptop Bag Fit Guide, which lists the interior and exterior dimensions of each size of the Vertical BrainCell, and compare the exterior dimensions of the Vertical Brain Cell tothe interior dimensions of your backpack to make sure it will fit.

    The Vertical Brain Cell has two front mesh pockets (designed to fit your power supply and other small accessories) as well as attachments for a shoulder strap, allowing you to use it as a stand-alone laptop bag.

    We offer two different shoulder straps that can be used with the Vertical Brain Cell: the Simple Shoulder Strap, a great choice for those who carry smaller, lighter laptops, and the Absolute Shoulder Strap, which offers the ultimate combination of a nonslip underside with the comfort of neoprene and an internal control-stretch system: a layer of elastic is sandwiched between layers of neoprene foam — the elastic controls the stretch.

    The Vertical Brain Cell comes in multiple sizes to fit a wide range oflaptops: four sizes designed specifically for Apple laptops (Size 4Z = 15" MacBook Pro, Size 6Z = 13" MacBook Pro, Size 1 = 17" MacBook Pro) and multiple different sizes for PC laptops. We recommend using our Laptop Bag Fit Guide to determine which size of Vertical Brain Cell you need for your laptop. If you can't find your laptop in our Laptop Bag Fit Guide, or if you have further questions, feel free to email or call us.

    Please note: In order to get the most laptop protection from theVertical Brain Cell, it must be carried in the vertical (portrait)position. Therefore, it is best to use this bag with the Smart Alec, Brain Bag, or your current backpack. If you require a protective laptop case to use with a briefcase or messenger bag, in a horizontal (landscape) position, please see our Horizontal Brain Cell.
