When we need a little extra storage for our bikepacking gear or bike essentials, the USWE Frame Bag is the perfect way to do it. Featuring a 2. 6-liter or 3. 4-liter capacity, the Frame Bag is available in two sizes and secures to the top tube of the bike through the use of hook-and-loop straps. The waterproof fabric keeps our gear inside safe and secure, and the interior zippered pockets keeps smaller items organized
