The Kickback II is slightly larger than our Kickback I and is designed to hold all of your 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 II 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 II truly unique. To give the Kickback II added stability on your top tube we engineered it with 3 points of attachment. Lone Peak has been producing technical cycling gear in the USA since 1979 and our products are built to last a lifetime. All Lone Peak products carry a lifetime guarantee against manufacturing defects for the original owner.
