Onyx Impulse A/M-33 All Clear Automatic/Manual Inflatable Life Jacket - Blue, Adult Universal (30-65 in Chest)

The Onyx Impulse A/M-33 All Clear Automatic/Manual Inflatable Life Jacket (part number 132800-500-004-21) is a Blue, adult universal-size personal flotation device designed for boaters who want a low-profile jacket with flexible inflation options. Inflation is triggered automatically by water contact or manually by pulling the inflation cord, and the included manual conversion cap lets you switch the jacket from automatic/manual mode to manual-only inflation. A front zipper closure keeps the profile slim and secure, while air mesh in the contact areas adds comfort against the skin. The inflation handle clips to the jacket body to prevent snag hazards, and a Quickburst zipper design makes repacking the inflation chamber easier after use. A status window shows green when the jacket is properly armed, giving an at-a-glance safety check before heading out. The inflation chamber carries SOLAS grade reflective material along with a light attachment point for visibility on the water. Fit is aided by dual adjustments with a belt keeper to manage excess webbing, a V-back design for faster donning, and a wider, more comfortable body belt. The protective cover is built from heavy-duty nylon and Cordura fabric for durability. This universal adult size fits chest sizes from 30 inches to 65 inches.
