Abstract: Coolagge is a hard shelled case with a removable liner and is insulated to hold items in their specific temperatures for a longer period of time. The removable liner zips and holds the original contents of the suitcase so it can be separated from the hard shell. The liner can also be used separately from the hard shell to hold items with it's own handles and shoulder strap. Coolagge can then be used as two separate items. Coolagge is lockable for transport,such as checked baggage, but can be opened for inspection. Coolagge also has wheels affixed to the bottom of the shell for walking transport, and is equipped with a collapsable handle to drag Coolagge on it's wheels. The hard shell also has handles on each side for lifting.
