Here is a video of one Vertx's multicam gear products... "Our MultiCam Smock  has everything an operational athlete will need on the go. Lets start at the top with the stand up collar and fleece lined button- down hood with 4 draw cord adjustments -- keep it ship shape by detaching the hood an rolling when not in use. Large chest pockets here with a concealed vertical zipper closure. Inside there are mag pockets, bellowed at the bottom for extra capacity.
If you need more storage for your mags, there is a side seam with single flap entry and a velcro closure, again these pockets are bellowed at the bottom for extra capacity as are the back pockets here with the single flat entry and Velcro closure. You can never have too many storage locations, low profile zippered underarm and down side seam to provide fluent access to contents. Sleeve pockets with concealed zippers and concealed zipper front to top of collar with Velcro closure.
The smock is great with your layering system, the mesh lined dual pull pit zips provide ventilation, mesh keeps snow and debris from entering jacket and also allows easier donning and doffing of jacket. Intuitive Velcro wrist closures keep the unwanted elements out. Gusset and articulation added to elbow area for maximum range of motion."
