The Zeroshock is a notebook sleeve made of high resistance polyurethane foam to protect from the occasional notebook dive. The manufacturer claims this type of polyurethane to be more pressure resistant than your normal, garden variety polyurethane, which allows it to absorb 100G of pressure more than a standard notebook sleeve. It also looks cool. Available in Sept. in 15-inch and 17-inch widescreen varieties. Comes in black and black.
