Mother Nature doesn't always play nice. Imagine being able to stay warm, dry and comfortable when conditions are less than optimal. By taking high quality 1000 fill power down and sheltering it with a weather resistant/breathable material, we can keep you drier than an average down garment. And more importantly, it keeps your down drier too. After all, it's those lofty 1000 fill power down plumes that are keeping you warm. Although this kind of construction may immediately inspire ideas of tackling epic days in blasting frigid conditions, the Ignis is more suited for cool to cold conditions when moisture could potentially cause problems. We see it as the perfect puffy to take just about anywhere.
