A match made for METCALF. The GRAVELLY 18 is three packs in one: + It’ll securely “piggyback” to your main bag, adding 18 more liters of capacity for critical gear. + Attach the GRAVELLY 18 to the frame and use the compression straps and Overload Shelf as a meat hauler while also carrying the essentials with you. + Use it as a stand-alone pack for a quick stalk or glassing session. #mysteryranch #builtforthemission
