Weighing in at just 344g, the Mezzalama Polartec® Alpha Jacket is the lightest insulating jacket in our line. It not only keeps you warm, but it also keeps out wind and moisture so you don’t get chilled. At the same time, it is breathable so moisture is wicked away from your body. Two large front pockets offer storage space, and reflectors lend safety in low light conditions or in the dark.
