This TOPEAK Aero Wedge Pack is the perfect addition to any cycling adventure. In the typical black color it is made from a durable combination of denier polyester and nylon. This bike bag features a zip closure, reflective strip, inner small net pocket and one large pocket for all your essentials (fits my IPhone 14 with room to spare). Measuring apx. 8 inches in length at its longest point, 5.5 inches in height at the opening, and 4 inches in width also at the mouth of the opening. This bag is both lightweight, stain and water-resistant, making it ideal for any weather condition. This lightly used bag is in very good (like new if you ask me) condition. No holes, stains, tears or defects. Please see pics for details of the condition as they are a part of the description. This TOPEAK bag is a must-have. Its softshell construction and expandable design make it both practical and stylish, while its behind-the-seat positioning keeps it out of the way while you ride.
