The Vertx Integrity Base Jacket is a lightweight, versatile piece which can be worn alone or layered with the Vertx Integrity 37.5 Waterproof Shell. Constructed of 100% nylon with a water-repelling nanosphere treated exterior and 68 grams of PrimaLoft insulation, this jacket is comfortable, durable and ideal for action on duty or off. Hand warmer pockets and a suede collar keep wearers comfortable when temperatures drop. Side insertions made with Polartec Powerstretch Hardface Fleece create ease of movement and a tailored, streamlined fit. The Base can be attached to Integrity Waterproof Shell as a liner or worn separately.
