The Jetpilot Quantum is a leap in vest design, built for the ultimate range of motion and flexibility. Ribbed segmentation and oversized armholes give freedom of movement as you've never seen, allowing jetskiers and wakeboarders to have 100% unhindered motion. Featuring Jetpilot's high-grade, environmentally friendly Ecoprene along with lightweight freelite foam, the Quantum feels soft to the touch and comfortable even when wet.
