A helmet having blunt force trauma protection includes a prior art helmet and a replaceable impact layer. The replaceable impact layer preferably includes at least one air bubble layer, a removable attachment system and an outer layer of sheet material. The at least one air bubble layer includes a plurality of air bubbles created between two plastic sheets. Each bubble will burst upon a pre-determined impact. The plurality of bubbles preferably have a hexagon shape, but other shapes may also be used, such as round or square. The removable attachment system is preferably hook and loop fasteners, but other suitable removable attachment systems may also be used. At least one first pad of hook and loop fasteners is attached to an exterior surface of a prior art helmet and at least one second pad of hook and loop fasteners is attached to a bottom surface of the replaceable impact layer.
