If your mission requires multiple climates the Jacket Stash Pocket will keep your layering system in an easily accessible location. VELCRO® brand fasteners are used to attach the pocket to the base of the back panel on the bottom of the envelop. The pocket includes drawstring closures and can be accessible from either side. When it is not in use the pocket can be rolled up and secured with a VELCRO® brand strap. The Jacket Stash Pocket can be used in conjunction with Horizontal Rear 5.56 Magazine Pouch or by itself. It will fit our vests and carriers that have VELCRO® brand closure on bottom of plate pocket with the exception of the SCARAB and the APC. All materials and workmanship are 100% made in the USA.
