The 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 for jetskiers and wakeboarders to have 100% unhindered motion. All new stretch neoprene and freelite foam give you the perfect fit with almost no weight behind the vest. Add in a Firefurr liner, allowing the vest to not only dry fast but keep you warm in the meantime.
