600D Oxford weatherproof bike saddle / triangle bag — 25 x 11 x 8 cm Key benefits Protects belongings on every ride: tough 600D Oxford cloth is weatherproof, tear-resistant, abrasion- and heat-resistant, and wipes clean easily from mud or sewage. Keeps items accessible and organized: large zipper opening and durable zipper provide quick access while riding. Stays securely in place: wide, adjustable straps create a strong contact area with the frame so the bag does not loosen or fall during rough or fast rides. Low profile and lightweight: slim housing and top-tube mounting reduce wind resistance and minimize leg rub for a more comfortable ride. Features Material: 600D Oxford cloth, weatherproof and easy to clean. Mounting: attaches under the top tube; adjustable straps for a tailored, stable fit. Design: slim triangle/saddle shape with large-capacity interior and wide zipper opening. Durability: tear-resistant, abrasion-resistant, heat-resistant fabric and robust zipper construction. Size: 25 x 11 x 8 cm — compact but roomy enough for essentials. Compatibility and performance Designed to fit most road, mountain, and commuter bikes when mounted under the top tube.
