The Super Spike Duffel integrates perfectly with the J-34 or F1 Mainframe Packs. Load all of your clothes and gear inside and carry it internally. When you arrive at camp, slip out the duffel and leave excess gear in your tent. Once you've bagged your game, load the meat inside the meat compartment, put your gear in the duffel and zip it or clip it on the outside and head off the mountain. A new level of versatility built for the hunter in mind. Available in Mountain Camo.
