The Nike ACG took a trip to Iceland to inspire this puffer jacket - so, yes, it's seriously warm. It’s made from water-resistant nylon and stuffed with Primaloft® insulation that's got your back even in the harshest weather. Its Therma-FIT tech keeps your body temperature just right, and the full-length zip and lofty padded hood? That's your extra shield against the elements. 100% Nylon Primaloft® Insulation Therma-FIT Technology 2 Side Pockets ACG Carabiner Packable Sack Included Full-Length Zip Printed Branding
