Conquer the land and sea with the Sea Shell “Charles D.” AETEM have created a great line of backpacks/waterboards that allow the sea trekker to travel minimally, in accordance with nature. Hand made using a robust carbon hard shell, the Sea Shell is an ocean worthy tool designed to excel both on land and sea. In water, the Sea Shell floats on a leash with little resistance due to its elaborate aqua-dynamic shape. On land, attach the backpack harnesses and the Sea Shell becomes a well weighted comfortable backpack. If your trek turns flat, adding the optional wheels to turn this backpack into a trolley. Weighing in between 3.5 – 7 kg, the Sea Shell is comprised of two separate gas and waterproof chambers (70L capacity) that are held closed using stable screw caps. If you have a little Jacques Cousteau in your blood and nothing is floating your boat these days, the Sea Shell by Aetem, is one great piece of innovative gear.
