Water resistant and windproof shell is made from a 20 denier, 24 high filament nylon fabric for a super soft feel and high tear resistance, keeping you insulated from the wind and rain. The reinforced shoulders allow you to carry skis, boards, and poles with sharp edges that would shred any ordinary down jacket. The reinforced nylon/spandex blend is also great for shouldering packs and other heavy gear. Lightweight underarm knit panels allow heat to escape for better climate control and comfort in a wide range of temperatures. The Spyfire jacket keeps you warm when the wind howls; dry when the skies spritz; and comfortable when the sun shines. The 800-fill goose down provides a superior warmth-to-weight ratio, protecting you from the elements without bogging you down. The down is certified non-force-fed and not live plucked.
