A backpack for transporting articles and for ballistic including at least one compartment and opposing straps vertically attached to a back-facing portion of the backpack. A first compartment includes a plurality of pouches disposed on an inner surface of the first compartment to store various accessories, a second compartment immediately behind the first compartment defines a cavity sized to receive a bullet-proof material, and a third compartment is formed between the second compartment and the back-facing portion and used to store or transport various articles. Once the user senses danger or comes under fire, the user may deploy the backpack as a ballistic protection by shifting the backpack from where the back-facing portion rests on the user's back side to where the back-facing portion rests on the user's front side. While in the ballistic protection mode, the straps remain situate on the user's shoulders so that both of the user's hands remain free to access accessories stored within the backpack and to utilize firearms if necessary.

Disclosed is a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position. The structural tube may include the top-tube or the bottom-tube of the bicycle. There is provided, in accordance with an embodiment of the present invention, a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position.

A convertible carrying device in which the straps may be selectively secured to configure the device as a backpack or as a handbag. In the handbag configurations, the selective securing of the straps effectuates differing functional strap lengths enabling the handbag to be carried by hand, over a shoulder, or cross body. The arrangement of the connection points on the bag and the straps applies directional forces to the placket surrounding the opening that make it adopt a valley shape when in a handbag configuration and a planar orientation when in the backpack configuration.
