Introducing the Ronix Neptune Junior and Atlantis Capella vest. Specially designed to fit young riders who are growing out of our youth series but haven't quite reached the weight and size of a teen. For the past few years, our team of 100 lb riders has been collecting data and working on developing the perfect fit. Now with this new model, you can get the same advanced technology as our other life vests, in a size that fits just right.
