Synthetic insulation jackets are a must have for anyone living in very cold or freezing weather conditions. Synthetic insulation jackets are built up from many layers that insure great warming, durability and safety. These jackets can be made from a wide variety of synthetic materials; like different types of nylon or polyester, PrimaLoft, thermic micro, thermal R or CoreLoft. An advantage of synthetic insulations is that they are all manmade, which means that they are hypo allergic and they offer a wide variety of styles and qualities. Synthetic insulation jackets can vary a lot in their warming abilities, weight, quality and material. So this offers you a wide range and also gives different prices to choose what you can afford. Synthetic insulation materials can be heavy and bulk, but they insure a great warmth that is difficult to ensure with other jackets. They can have zippered pockets internally and externally that can be zipped for safety, they can be hooded for extra head protections and with high collars to fully protect the throat. They are available in varied colors to suit all styles.
