The new, stealthy lid is made from the same food grade polycarbonate that our Original Polar Blast lid is made from. Contents can be concealable in the sunken in space and the lid top is detachable. At the bottom of the dual, walled stainless steel insulated tumbler is an additional removable compartment. It is a 2 in 1 stash area and grinder. This is also made from our durable food grade polycarbonate and is sure not to break.
