The tall, narrow pockets on our J-Type packs are proven as a great way to stay organized. Because they don't have a lot of lateral space, things tend not to jumble around as you go through your pace. We like to think of each tube as a three-tiered space: bulk on the bottom, bulk on the top, and your apples, oranges, and widgets in the middle. When it's time to look for you apple, it'll be right where you put it, easy as that.
Now comes the fun part: you can add a tube or two to just about any of our packs with our new A6SB Batwing Pouch. Think of the opportunities. Use two of them with the F1-Mainframe, and shazzam you've got a great minimalist version of our patented Cam Expansion packs, ready for a day's hunting interrupted by a harvest of a giant you-name-it. Or, add them to a J-type pack to add a third or fourth tube as a handy and simple way to increase capacity.
Each Batwing features a wrap-around zipper for access, internal hydration sleeve (add one of our Source bladders!), attachment zippers compatible with our modular system, external tuck-pocket, and webbing loops running down the backside that give you the option of hanging the Batwing on your Eberlestock pack's grapple straps.
