The Alpha® Switch Pullover Jacket is a reversible, insulated multi-tool for your outerwear quiver. It features a stretch woven material on one side, and translucent, DWR ripstop on the other side. In between, it's layered with 80g of continuous (vs baffle) Polartec(R) Alpha(R) insulation. Here's the scoop: Alpha(R) was developed for U.S. Special Ops Forces, and was recently de-classified. Spun in Polartec's Massachusetts factory, it dries 60% faster and is more breathable than other synthetic insulations. Perfect for boot-packing up Old Glory then kicking it back down. 5 pockets. Reversible zipper.
