I searched online for the Sentinel mask thinking maybe it was an April fools joke. While reading, they claim that they chose to use Brians name because according to their site, and in their words, Brians is a small company that "needs a competitive edge', "lacks a current mask offering", "has a history of innovation", "has massive street cred", and they also say that Brians was "once a maker of the finest gear available, recent economic turmoil and strong well financed competitors has severely diminished market share."
I serioulsly doubt Brian's would have any interest in this mask, and wouldn't care for their comments.
