The Kickback I is our original top tube bag. Made to hold the essentials, like smart phone, wallet, food and tools, keeping them safe from the elements. We placed high-density padding in the sides and bottom to protect your items and to ensure the Kickback I keeps its aerodynamic shape. To keep the moisture out, we use a piece of recycled inner tube across the top of the zipper, making every Kickback I truly unique. To give the Kickback I added stability on your top tube we engineered it with 3 points of attachment. If you happen to be looking for a top tube bag that is slightly larger, check out our Kickback II.
