The Kuhl Men's Spyfire Down Vest combines superior fabrics, articulated patterning and thermal body mapping to deliver technical performance with unparalleled style! Three unique fabrics, each engineered for a specific purpose, differentiates the down from others. MIKROTEX nylon shell is woven extremely tight to provide durable down proofing with wind and water-resistance. Body front has an additional over-lay for extra protection against the elements. TUFFLEX softshell reinforced shoulders allows you to carry skis or equipment that would shred any ordinary down sweater. Lightweight underarm knit panels allow heat to escape for better climate control and comfort in a wide range of temperatures. The responsibly sourced (non-force-fed/not 'live-plucked') 800-fill goose down provides a superior warmth-to-weight ratio. With thermal body mapping design, the larger baffles at front and back body provide core warmth. The thinner, sized-down baffles on the side body provide a contoured fit and reduce bulk for improved layering.
