The Fly Direct Jacket combines an ultralight construction with Polartec® Alpha® Direct insulation to create an incredibly warm garment. Its lightweight design allows it to be easily packed into a pocket or backpack when the temperature changes. To create this garment, we start with an ultralight windproof shell treated with a DWR (durable water repellent) finish for protection against wet roads or unexpected downpours. We then combine this shell with Polartec® Alpha® Direct insulation, which is incredibly warm and breathable despite its low weight. A YKK® Vislon® zipper on the front opens from both the top and bottom and slides smoothly for optimal temperature regulation in changing weather conditions. Three storage pockets on the back allow you to carry all your essentials. Finally, reflective elements at the waist and cuffs ensure maximum visibility. Overall, this makes the Fly Direct Jacket the ultimate winter jacket, where weight, warmth, and compressibility take precedence over everything else.
