The Fly Direct W Jacket combines super-lightweight construction with Polartec® Alpha® Direct insulation to create an amazingly warm jacket. Its lightweight overall construction means that if the temperature changes it can be easily stashed in a pocket or frame bag. To create this piece, we start with an ultralightweight windproof shell that is DWR treated in case you encounter wet roads or a quick rain shower. Then we pair the shell with Polartec® Alpha® Direct insulation, which is unbelievably warm and breathable for its weight. On the front we use a top- and bottom-opening YKK® Vislon® zipper that is easy sliding for convenient temperature regulation if the intensity starts to tick up. On the back are three pockets for storage to make sure you can carry whatever you might need. Finally, we add reflectivity at the waist and wrists for visibility. Altogether, this makes the Fly Direct W Jacket the go-to winter jacket when weight, warmth, and packability are important.
