ABSTRACT:
A system for maintaining a user afloat in a fluid environment is disclosed. The system includes multiple chambers such that if one chamber fails to operate, redundant chambers will function to maintain the user afloat in a face-up position. In a preferred embodiment, there are multiple activation mechanisms to ensure inflation of the chambers if a single activation mechanism fails to function.
