A running belt that transforms into (almost) anything! Okay, while admittedly, it can't become a rocket ship, your Amphipod R3 Express Convertible Pack can be worn as a bounce-free waistpack one day or crossbody bag the next! Secure essentials with the internal divider and plug your earbuds through the fob for on-the-go listening. The breathable and moisture-wicking design is sleek and comfortable. And with 1.1L of storage, this lightweight and convenient accessory encourages all adventures.
