Abstract
A back pack has a base member for facing the back of a wearer with a raised peripheral rim, and an outer shell of rigid material for facing away from the back of the wearer, the base member and outer shell together defining an enclosure for containing items to be carried. The outer shell has an integral peripheral rim bent towards the base member, and a zipper fastener is secured directly between the peripheral rims of the base member and outer shell and extends around at least a major portion of the rims to provide a secure closure as well as easy access to the enclosure.
