  • The PRO LT 4000 has the capacity to carry large optics and cold weather gear for later-season day hunts. For the minimalist hunter, this is the perfect pack for 2-3-day bivy style hunts. The pack bag features a main compartment with a full horseshoe zip, two front zippered pockets and two side stuff-it pockets.

    The fabric choice and placement has been optimized and features more durable and waterproof fabrics in key areas along the back and bottom of the bag. A new side zip front pocket allows access to often needed items even with a gun or bow attached.

    All load bearing zippers have been upsized to a robust YKK #10, and laser-cut, hypalon attachment points for compression straps minimize weight and build. New webbing loop locations provide improved attachment for gun and bow holders.

    The PRO LT is easily transitioned into Load Sling Mode, which opens an extra 2500 cubic inches of storage for hauling meat or gear between the frame and bag. Combine this feature with KUIU Game and Gear bags to complete the system.
