We won the Best Large Handlebar Bag by !
The Jumbo Jammer is a high-volume, rack-less, and weatherproof handlebar bag. This massive bag is the largest in our Jammer line and is perfect for bike-packing, road touring, and commuting. Load it up with the essentials and use the cargo straps (included) to strap even more on top!
When fully expanded, the Jammer will reach up to 26L in volume and be rolled down to more than half of that. Yeah, 26 liters! You'll believe it when you see it.

About our C.W.S.
The Anywhere Bikepacking Panniers use a roll-top closure and dual vertical adjusting straps. We call this our C.W.S.: Closure Webbing System. The C.W.S. creates a 4-point compression (as shown in the photos above) and works to keep the bag cinched tight and give it the 4th mounting point (around the top or side rails of your rack), which then eliminates any sway and sag there may be when loaded. Next, remove the webbing strap from the D-rings, re-string the webbing around the point of interest, then back to the bottom D-ring and up to the roll-top closure buckle.
