The Nike CommVest was designed specifically for mountain search and rescue operations with a focus on pure function. The designers worked extensively with rescuers to understand their needs and the problems with existing equipment. As a result, the CommVest is the first such product to fully accomodate the actual activity of the user and how they interact with technology. In addition to cutting-edge waterproof/breathable materials, the designers utilized conductive fibers and smart fabrics in order to integrate essential radio functions into the vest.
