SIERRA ADV GEAR has worked with top bag designers to make the ultimate motorcycle folding compact backpack to keep on your bike from putting it in a side box or tank back. When you stop, you always have a bag onboard so you can hit the town in fashion or hit those areas you just have to hike to. Pack them with water, snacks or put some groceries in to ride back home. A must-have for the ADV rider.
This bag turns from a 7 x 7, 2-inch little bag into a 18-liter mid-size back pack.

Comes in 5 colors:
Black, gray, orange, blue and green.
