PrimaLoft® One is the ultimate microfiber insulation. Ultra-fine fibers are specially treated in a patented process and then combined into an insulating core that is incredibly soft, lightweight and water resistant. PrimaLoft® One absorbs 3 times less water, is 14% warmer when dry and is 24% warmer when wet than the competitive insulation.

The human body is 98.6 degrees Fahrenheit but often ends up in places that threaten to make it far colder than that! PrimaLoft® insulates your body to keep it comfortable and conserve energy even in extreme cold.
