The Heat Reflective Shell - Insulated™ (HRS-I™), a rugged outer shell is constructed of a 5-ply composite fabric with a protected non-conductive reflective layer and NEW insulation layer that provides additional thermal retention. Rapid 360° access to the casualty with minimal exposure to the elements is achieved through the use of 1.5 in. continuous hook and loop closures located along the perimeter of the covering.
The new insulation layer in both the top and bottom of the HRS-I™ exceeds the insulation value of the Army Module Sleep System Patrol Bag. This insulation is highly compressible but also has excellent rebound after opening. The added insulation is also hydrophobic and will not retain fluids or additional liquid weight while maintaining insulation properties.
