The Helios 2.0 is a life jacket for those water enthusiasts who are looking for a low-profile, inflatable option for sailing, racing, and fishing. The Helios 2.0 features an ergonomic collar with a neoprene neck panel to mitigate chafing and stay comfy. On-water necessities are easily attached to the webbing loops, D-ring, or tucked safely in the zippered storage pocket. Use the indicator window to check the jacket's arming status before heading out. The Helios 2.0 comes with one bayonet-style CO2 cylinder. This product must be shipped via ground delivery services due to the included CO2 cylinder.
