Types of men's active performance insulated jackets
The type of insulation used is the most important factor to consider when choosing between high-performance insulated jackets. The three major ones used in cold weather jackets are down, synthetic, and hybrid insulation. Down comes from the fluffy feathers of geese and ducks, while synthetic insulation is mostly plasticized polyester fibers. Jackets that use hybrid insulation combine down and synthetic insulating materials.
