Gently used. Great condition. No outward signs of wear. Made in a stretch 2L fabric using technical bonded construction, the down channels of this hooded jacket are fused together, sans sewing, to maximize water-resistance and prevent any down for escaping. While PrimaLoft Gold insulation is used at the side panels to reduce bulk without sacrificing warmth, the real magic in the jacket is the water-resistant 700 fill-power genuine traceable down that is both water resistant and treated with a natural particle-based thermoreactive nano-coating. About the IR Active Water Resistant Down ThermaDown™ utilizes a natural particle-based thermoreactive nano-coating that, through the emission of infrared energy, increases the natural benefits of down. Using body heat as a catalyst, the ThermaDown™ IR active down utilizes a body’s emitted heat by trapping that energy in the particles coated on the down and transmitting it back within the high-infrared spectrum. This infrared energy is easily absorbed back into the body providing all the benefits of infrared subcutaneous absorption – gently increasing circulation helping to re-oxygenate muscles and keep the body temperate. HyperDRY™ was developed using nanotechnology to create the most effective water resistant down on the market. These methods provide an invisible coating that does not compromise the texture or warmth of the down.
