Motorcycle bag

A bag attachable to a variety of different sized motorcycle back rests that vary in width and length by an attachment system permanently fastened to the bag, said attachment system comprising:

• a panel on one side of the bag, the panel having a top, a bottom, a first end fastened to the bag, and a second end fastened to the bag, the panel and the bag defining a closed loop containing a space adapted to fit over a motorcycle back rest;
• a releasable closure mechanism on the panel extending from the top to the bottom of the panel, the closure mechanism reducing the closed loop when closed;
• a covering having an opening sized to fit snugly over the motorcycle bag;
• a compartment on the motorcycle bag for concealing the covering when not in use;
• a tether connecting the covering to the inside of the compartment;
• and
• a pair of arm straps releasably connectable to the motorcycle bag, said arm straps storable in a compartment on said motorcycle bag when not in use;
• whereby the panel fits over a back rest of a first size when the closure mechanism is closed and the panel fits over a back rest of a second larger size when the closure mechanism is open, wherein there is no bag on the other side of the closed loop.

A bag attachable to a variety of different sized motorcycle back rests that vary in width and length, the bag comprising:

• a bag body having an openable and closable internal compartment configured for storing items;
• an adjustable attachment system secured to the bag body, the adjustable attachment system being configured to allow the bag body to be secured to a variety of different sized motorcycle back rests that vary at least in width, the adjustable attachment system comprising:
• at least one panel of material secured to an exterior portion of the bag body, the at least one panel of pliable material having a first end and a second end, the first and second ends of the at least one panel of pliable material being secured to the bag body, the at least one panel of pliable material further comprising at least one upper edge and at least one lower edge, at least portions of the at least one upper edge and at least one lower edge being free, the at least one panel of pliable material thereby forming at least a portion of a closed loop, wherein the at least one panel has a front surface extending between the first end and the second end, and the front surface has a width greater than the width of the bag between the first and second ends, and the front surface is sized such that the closed loop can be fit over a backrest of a motorcycle such that the backrest extends through the at least one upper free edge and the at least one lower free edge, wherein there is no other bag body attached to the at least one panel of pliable material;
• and
• a pliable panel tightening mechanism configured to change the circumferential length of the at least one panel of pliable material so as to allow the closed loop to be tightened around a motorcycle back rest, the pliable panel tightening mechanism being configured to act on the at least one panel of pliable material to, in a first state of the pliable panel tightening mechanism, allow the closed loop to take a first circumferential size and to, in a second state of the pliable panel tightening mechanism, allow the closed loop to take a second circumferential size in which the maximum circumferential size of the closed loop is limited to a size that is smaller than the first circumferential size;
• whereby the closed loop tightly fits over a motorcycle backrest of a first size when the pliable panel tightening mechanism is in the first state thereby allowing the bag to be securely attached to a first size backrest of a motorcycle and whereby the closed loop tightly fits over a backrest of a second smaller size when the pliable panel tightening mechanism is in the second state, thereby allowing the bag to be securely attached to a second size backrest of a motorcycle, the second size backrest being smaller than the first size backrest.
