The different styles in the Astral series include a range of options to suit all types of paddling, but every vest is constructed with a keen focus on ergonomics and protection. The soft flotation foam is shaped by hand, and wraps around your body like a custom-fit shirt. The front panels are cut low and thin at the top to give you all the freedom you need. Back panels are cut wide down low to protect your ribs, and narrow up high to protect your spine without hindering the movement of your arms. Thanks to Astral's innovative shoulder-strap geometry, the vest stays put no matter how you move your arms. The straps stretch, allowing the body of the PFD to stay "anchored" on your torso.
