This is a four-chamber collar utilizing our patentef foam/air hybrid system. When fully inflated, it looks and feels like an air collar.

In this photo, the starboard-side air chambers are completely deflated, showing the internal foam structure.

Our unique zipper system allows for unparalleled ease to each of the air bladders. If you ever puncture the bladder and need to repair it, this makes the job quick and easy.

Our system allows for easy removal of the air chambers in the event you need to patch, repair, or replace it.
