Another great product from Snugpak. The insulation level is about perfect for 20 to 40 degrees Fahrenheit. Not as long as the 12, which allows quick access to a holster or other gear.. Very well thought out jacket perfect for 2 x a day hour plus walks with the doggo. Camouflage shipped it out on a Monday, and I received it on Tuesday here in America. Best shop in the world to do business with.
