The amphibian survival backpack is used to house various equipment the wearer will require while traversing aquatic environments. The backpack, made of the same durable materials as the survival suit, provides the same lightweight, sturdy characteristics. Providing room for a supply tank of air and enough extra space for the user to carry a small assortment of other tools, the benefits of the backpack are only fully realized when paired with an amphibian survival suit and mask. Once combined with these other components, the wearer is protected from the harsh elements found in watery terrains.
