Amphibious Upbags are a great space saving addition to your luggage needs. Just when you thought more room was hard to come by, Upbags are here to solve that problem. These bags share the same design characteristics as the Amphibious Motobag and can be used as you see fit. However, the most common use is to strap these down on top of already installed side luggage. This saves you from taking up the space across the top of the bike where a passenger would sit.These bags are sold individually so it would be ideal to purchase two for one bike. The size ranges from 9 to 19 liters in capacity thanks to the air valve that allows a slim fit so no air is trapped inside. Bags are reinforced on the bottom to ensure ruggedness and have 8 reflective strips for visibility from each angle. A carrying handle made of Cordura fabric makes for easy transportation when off the bike.Approximate Upbag Dimensions (LxWxH):5.5"-11.8" x 12.6" x 7.9"
