The KUHL Men's Spyfire Down Vest combines superior fabrics, articulated patterning, and thermal body mapping to deliver high performance with unmatched 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. The body front has an additional overlay for extra protection against the elements. TUFFLEX softshell reinforced shoulders allow 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 the front and back body provide core warmth. The KUHL Men's Spyfire Down Vest features thinner, sized-down baffles on the side body that provide a contoured fit and reduce bulk for improved layering.
