The Vertx® Integrity Base is the foundational piece you can rely on when building out your cold-weather kit. Its streamlined design and lightweight construction take advantage of an efficient barrier of PrimaLoft® insulation to hold chills at bay when it’s worn alone or when it integrates into the Integrity Shell and Recon Jackets for additional protection from cold and wet weather. With its water- and stain-resistant nylon shell and quiet gusseted Polartec® Hardface stretch fleece side panels, the Integrity Base Jacket won’t bind, restrict or announce your movements. Snug stretch cuffs and the zip-through polyester suede-lined collar puts the icing on the cake by effectively and comfortably sealing icy blasts on the outside. When temps are low, keep your performance high in the Integrity Base Jacket.
