Know before you buy
The bag is designed to attach securely to almost any standard bicycle rear rack using a universal mounting system. It is highly compatible with most commuter and touring racks, but it is not intended for racks with specialized proprietary mounting hardware.
The bag offers a total capacity of 15 liters when fully expanded. This is plenty of space for a change of clothes, a lunch, and a few tools, making it ideal for daily commuting or shorter weekend trips.
Yes, the interior is insulated to help maintain the temperature of your food and beverages. While it is not a hard-sided cooler, it works well for keeping snacks and drinks cool during a standard commute or a few hours on the road.
The bag features a rugged, ballistic nylon base that provides a solid foundation on your rack. When strapped down properly, it remains stable and secure, even when you are riding over uneven pavement or bumpy city streets.
Yes, there is an integrated clip on the back of the bag specifically designed for attaching a rear safety light. This placement ensures your light is visible to traffic behind you, especially in low-light conditions.
The bag is constructed from durable ripstop fabric and ballistic nylon, which are water-resistant and capable of handling light rain or road spray. However, it is not fully waterproof, so you should use a rain cover if you are riding in heavy, sustained downpours.
