The Simms Fall Run Jacket is as light as a feather but warm like your favorite sleeping bag. We love these jackets and find the packability a very nice feature. Wear the Fall Run Jacket under your rain jacket for all-day warmth in the coldest conditions. If it gets warm, it packs down to small enough to stick in the pocket of most packs. The wind resistance and water repellency are good enough to wear the Fall Run by itself in most spring/fall conditions and this jacket is so comfortable, you'll probably find yourself wearing it around town as well.
Here is what Simms has to say about the Fall Run Jacket:
Fall migrations go in several directions: Upstream for giant browns en route to their natal dancing grounds. And virtually any points north, east, south, and west, depending on which direction you travel to intercept banner autumn fishing. Wherever you roam, throw on Simms’ Fall Run Jacket for lightweight, packable performance in the form of PrimaLoft® ONE insulation. Jackets feature a winning warmth-to-weight ratio and the water repellency to take on wet conditions the world over.
