We often wonder if there will come a time when we run out of new ways to get an adrenaline rush in the great outdoors. While companies are busy cramming more “hours” into our energy drinks, we worry that we’ll hit the limit of natural epinephrine injections. Just when we begin to worry that snowboarding and waterskiing are the limits to our adventures, there comes along a product like Subwing. The two carbon fiber wings along with the detachable center swivel lets you—in a sense—fly through the water. Subwing gives you the ability to navigate both up and down and side-to-side so you can skim the ocean floor and experience a whole new rush. Boat to pull you not included.
