The Hewes Bluestorm Cirrus 26 Inflatable Life Jacket is a US Coast Guard Approved Type V PFD offering Type III performance. It automatically inflates upon water immersion using a replaceable CO2 cylinder, providing 26 pounds of buoyancy for reliable flotation. The automatic inflation can be manually disabled or triggered by pulling the jerk cord. Its slimline chassis positions the adjustable strap and buckle lower on the ribcage to prevent riding up, while the mesh back strap yoke ensures a comfortable fit by pulling the vest away from the neckline, reducing rubbing and irritation during extended wear.
