The Alpinist Hybrid Jacket is a technical layering piece that excels in frigid temps thanks to Primaloft® One insulation in front and Polartec® Power Stretch Pro® in sleeves, back and hood. Underarm thermo-regulating panels reduce bulk; scuba-style hood is stretchy and lightweight for use under a shell or helmet.
PrimaLoft® ONE insulation technology is the highest performing insulation on the market for warmth, water resistance, softness and compressibility.
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.
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.
Ultra-fine fibers form tiny air pockets that trap body heat and keep the cold out. The result is immediate warmth without the bulk. PrimaLoft® ONE Microfibers are engineered for permanent water resistance and create tight surface tension that resists moisture penetration, resulting in an insulation that dries faster than goose down. Ultra-fine fibers mimic the compressibility of goose down and are breathable, allowing moisture vapor to be transported through the fibers and away from the skin.
PrimaLoft One absorbs 3 times less water, is 14% warmer when dry and is 24% warmer when wet than the competitive insulation. It dries faster than down, but is just as warm, soft and compressible. It's lightweight, breathable and wind resistant.
Polartec® Power Stretch® Pro™ fabrics feature body-hugging 4-way stretch and are very breathable. They keep you dry when you sweat and provide warmth without weight. These fabrics feature a proprietary construction with two unique surfaces: a durable nylon outer layer is wind and abrasion resistant; the soft polyester inner layer pulls moisture away from your skin keeping you dry, warm and comfortable. The fabrics excel at handling the demands of the next-to-skin environment.
