This is an ultralight hoodie built with Polartec Alpha Direct 4008 fabric. 4008 Polartec Alpha Direct fabric is the next step up in warmth from the 4004 version. It has the same open structure for extreme breathability, but with more fibers in the “tufts” for more warmth. This is an excellent intense activity insulation layer that pairs perfectly with an Argon wind shell for a very light, modular system. The structure of the fabric is very open, with fluffy tufts between. When you aren’t moving it keeps you very warm. When you are working hard and moving your excess body heat and moisture moves freely through the fabric to the outside. You can instantly feel this action when you put one on. If you stand still it feels very warm. Swing your arm, even just a little bit and you can feel the air cool you. Obviously, due to this action, it will not do much to insulate you if it is windy, as the wind cuts through it like it isn’t even there. That is why it is best paired with an Argon wind shell. The combination together becomes a warm, versatile, and modular system. The Argon wind shell alone is enough to insulate a little bit and protect you from evaporative cooling in high winds while remaining fairly breathable (40CFM). The Alpha Direct alone will insulate you when you’re working hard and need really high breathability. Put the two together and you get a very warm system when winds kick up and the temp really drops or you want static insulation at camp. This can’t compare to a true static insulator like a puffy, but with a total weight around 9 ounces for the two, they cover a lot of conditions and have enough warmth to function as a static insulator at camp.
