The Talon Notebook Case, the successor to the ZeroShock line of notebook cases, is composed of a high-resistance polyurethane memory foam that provides superior absorption of external impact force. Favored by NASA and the U.S. military, the application of high-resistance polyurethane technology to notebook cases results in an unparalleled shock-absorption/weight ratio. Translation? Stronger protection for your laptop computer with less weight to lug around.
