Sun Mountain Granite Jacket and Vest are more than just another puffy. Granite uses 37.5 insulation which retains body heat while preventing moisture build-up and overheating — making it perfect for chilly days on and off the course.
The insulation in this puffy jacket and vest is 37.5, a patented technology that works to maintain an ideal core temperature. The sixty-gram insulation retains body heat, while active particles embedded in the insulation accelerate vapor movement to prevent overheating and moisture build-up. Further, 37.5 technology resists odors and is permanent and never washes out or gets tired. Bottom-line, 37.5 allows you to wear a puffy to keep the chill off without overheating in moderate conditions.
