The 17" laptop brief is made for people with larger computers and electronic notebooks. Although the size is bigger, models are still made of light-weight materials such as polyester, canvas or nylon. For the most expensive looking, professional and durable brief, choose one made from leather. Traditional cases that resemble a briefcase or messenger bag will have a removable, adjustable shoulder strap and carrying handles. Other models also have wheels and a telescoping handle, so the user can pull heavier loads. Many 17" laptop brief models can be easily adjusted to accommodate smaller laptops. Interior padding absorbs shock, keeps moisture out and ensures that the screen does not get scratched or damaged. Multiple internal compartments enable the user to transport accessories like a wireless mouse, battery, power adapter, disks and extra cable. External pockets with Velcro closures or snaps provide easy access to frequently used items such as a cell phone, headset, water bottle or wallet.
