This will take your breath away.
In a gorgeously shot video (above) for Steinlager Pure beer, freediving star William Trubridge looks like a man with gills as he plunges -- without air tanks -- into the depths of the sea.
Trubridge appears almost otherworldly, swimming down, down, down into an abyss called Dean's Blue Hole, located in the Bahamas.
In December 2010, Trubridge reportedly became the first man to freedive 100 meters (328 feet) without assistance and has gone deeper since.
To augment its "Born To Defy" campaign, Steinlager provided a get-to-know Trubridge segment, which you can check out below.
