Designed to fit Engel's MT60 fridge freezer, the Engel Transit Bag is more than just a heavy-duty canvas bag. It is heavily insulated so that overnight it helps lock in the cool air generated from the day. The canvas bag also contains storage pockets on the side. The Engel Transit Bag can be kept on all day and all night to keep your fridge freezer protected and well insulated, which helps reduce the energy it uses.
