If you're going to own just one hunting pack to do it all, own Just One. Starting at an ultra-compact 2,300 cubic inches, the built-in Cam Expansion system unzips down the middle and opens up to a compartment with a whopping 4,600-cu. in. capacity. Add a Super Spike Duffel (sold separately), and you've instantly converted it into a mammoth 7,500-cu. in. hauler. Strategically placed MOLLE webbing lets you easily mount accessories, plus makes for easy lashing of bulky loads.
