What Is Primaloft Insulation?


Dealing with nature’s unpredictable weather patterns and fluctuating outdoor temperatures makes packing for camping, hunting and hiking trips a challenge. If you love exploring the outdoors during the cooler months, you need to keep your core body temperature stable to prevent hypothermia. Products containing PrimaLoft insulation help keep you warm and dry when exposed to the elements so your body stays healthy and your mind isn’t distracted by numb fingers and toes.


  • Albany International, in Albany, NY, is the parent company of the PrimaLoft manufacturing division. The technology behind PrimaLoft insulation resulted from a contract between the U.S. Army and Albany International. The Army was exploring types of insulation technology that would retain heat like traditional down insulation, but also resist water from precipitation.


  • PrimaLoft designed its One and Sport insulation to withstand extreme outdoor conditions, with advanced drying ability. PrimaLoft’s Synergy insulation features multiple unbroken layers of fiber, which means that the insulation won’t become bulky or sparse in spots over time. PrimaLoft also manufactures Eco insulation, used in garments and footwear, which contains fibers made from recycled consumer materials. PrimaLoft’s Infinity insulation uses continually connected fibers to create a supremely soft texture. PrimaLoft also manufactures yarn that also has water-resistant characteristics.


  • The fibers that make up PrimaLoft have a fine texture that produces small air pockets. The resulting insulation works to retain body heat and repel water. The fine texture also makes the insulation softer than fillings such as polyester. Albany International designed PrimaLoft insulation to imitate the texture of down feather filling. The texture of the fibers that make up the insulation allows for compression. Garments made with PrimaLoft require less space when packed in a backpack or suitcase.


  • Dozens of brand-name manufacturers use PrimaLoft insulation. Types of outdoor gear that feature PrimaLoft insulation include sleeping bags and outerwear such as parkas, pantsuits and gloves. Additional consumer products include sweaters, boots, socks and winter sport accessories. Branches of the U.S. military also continue to use PrimaLoft insulation in combat gear. Manufacturers also use PrimaLoft insulation in bedding, such as comforters, to act as an alternative to down stuffing.
