Ronix Pulse Capella Life JacketBack in the day they figured out the Earth isn't flat. Why did it take this long to realize your life jacket shouldn't be either? Seriously, this baby won't even lay flat, which is why it is called the Ronix Pulse Capella Vest. This latest life vest has a foundation sewn from 5 panels for more rib protection and a truly round fit. Back in the 1400's, when everybody was saying if you sail in one direction for too long, you will fall off the face of the Earth, but Capella and his homies knew otherwise. Smart cats, and Ronix is trying to pick up where they left off with their latest life jacket design. The function of this extra rib protected vest is that you have a seam running diagonally across your body, allowing movement that was only previously reached by tree inhabiting primates. The result, a vest contoured to your body, flexing with a rider during an aerial assault without any hindrance. Freedom of mobility that was once only harvested from the greatness of those non buoyant impact jackets. Changing the way you think about legalized flotation. Trust us you need to try it on.
