The Cramer Sports Medicine Dual Density Foam Kit consists of four layers of foam, each of which is a dual density layer formed by laminating together high and low density layers. Each sheet is 11 1/2″ wide by 11 1/2″ long. Two sheets each have a 1/8″ thick high density layer combined with a 1/4″ low density layer. The other two each have a 1/4″ high density layer combined with a 1/2″ low density layer.
The Cramer Sports Medicine Dual Density Foam Kit combines the advantages of high density foam (protection from high velocity impact) and low density foam (greater comfort). The low density layer is softer and helps to diffuse pressure. At the same time, the harder high density side absorbs impacts. The dual density foam therefore eliminates the need for two separate layers of differing densities.
