The Centerfire Series incorporates a stout 10 oz. Cotton Duck shell, and 8-Pointer riveted construction for durability. For comfort, the Sip 'n Zip aids mobility to enjoy reading or sipping while in the sleeping bag and the Downwind foot vent can be opened for added ventilation on warm nights. The removable integrated duffle bag can be stuffed and used as a pillow; and when ready to take-down camp, just roll the bag into the duffle, secure with the internal compression straps, and zip closded. Transporting such a beast of a bag has never been easier.
