The Zip-Thru Corporate Traveler Laptop Case is constructed of what Targus calls “durable ballistic 1680 denier nylon.” The lightweight material appears to be tough enough to endure the usual wear and tear, especially since this bag will never be checked-in; it’s designed to be a carry-on. Even so, I found that it was a fair bit larger than some of the other bags on the market. This can be a pro or a con, depending on your perspective.
