The USWE Top Tube Bag is our favorite storage option for bikepacking trips, gravel rides, and mountain bike adventures. No matter where our ride takes us, this durable, waterproof bag keeps our gear safe and dry with a fleece-lined interior, welded construction, and Hypalon front. The two elastic straps connect easily to the top tube with a hook-and-loop strap on the front to confidently secure the pack to our bike.
