The Nike SB Down Pack Vest Jacket keeps your core warm in the most frigid conditions. The lightweight goose down insulation holds heat in, while also having the ability to be densely compressed into the jackets' own pocket. The DWR coated nylon lets the water roll off, and the high collar and adjustable hem help to keep the elements from sneaking in.

Down - Down is the lightest and warmest option when it comes to outerwear insulation, the only drawbacks with down is it doesn't perform well in wet conditions and it's more expensive. Synthetics will dry faster than down and are easier to clean, but can't beat down when it comes to performing in very cold and dry weather.
A fill power rating measures the number of cubic inches that one ounce of that particular down will occupy, so a jacket with a 800 fill power rating will be warmer than a jacket with a fill power rating of 500.
Water Resistant Fabric - A DWR (Durable Water Repellent) finish allows fabric to shed moisture and prevents saturation to keep you warmer. DWR also helps repel oils and stains which can affect the fabric's breathability. Clothing with a DWR finish is a must in snowy or wet conditions.
