The new large "gas-tank" style top tube bag is the bag you've been looking for. 65 cubic inches of storage front and center of your bike's cockpit. 50% larger than our original #01062, this bag will hold a lot of what you need. Maybe that's food, or wallet, keys and phone, or heck, we've even heard some trail-riders out east use the bag to hold their concealed firearm. With a rigid bottom and padded sides the bag holds its shape and the main compartment zipper and side zipper are easy to use one-handed. We use the same weather-proof zipper system that we use on our frame packs. Reflective piping. Cut-to-fit straps means the bag will work on virtually any frame. The bag itself is not waterproof, but the fabric is waterproof and the zippers are covered. For the money the bag provides protection to satisfy riding in real-world conditions. Can also be attached at the seat-post.
