Granite is not just another puffy. The Granite has 37.5® sixty-gram insulation which retains body heat, while 37.5 active particles embedded in the insulation accelerate vapor movement and prevent overheating and moisture build-up. 37.5 allows you to wear a puffy without overheating in moderate conditions. Further, 37.5 technology is permanent and never washes out or gets tired.
