If you ride, the Spin Cycle Bag is a must-have. This lightweight, packable bag is a sidekick for your gear bag. Use it to separate your dirty riding gear from your clean gear, so it's ready to wash.When the bag is unpacked, it becomes a fully functional backpack with a large main compartment, mid-level zip pocket, and top quick access pocket. So, in a pinch, it can be used for unexpected trips to the store or on a short hike. The lightweight design allows the bag to neatly pack down into a small pouch so you can store it in your car or gear bag. If you're a cyclist, the bag will easily fit in your back jersey pocket.
