A perfect compliment to your F1 Mainframe™, or J34 Just One™ pack. Increase capacity of any of these systems by zipping in either size dry bag for a lightweight load hauler. The roll-top lets you compress your load down and the taped seams keeps your gear dry.
Combine the J2DB/J3DB with a pair of Batwing Pouches™ to make a lightweight, capable, meat-hauling day pack.

Great addition to my backcountry setup. Just returned from a snowshoe trip and this kept everything dry. The size is enormous. Easily pairs with the F1 mainframe.
Looks great snd installs easy gonna be a great addition to my F1 frame and bat wings.
These bags are tough and light. Not as heavy weight as a traditional dry bag which saves weight but way stronger than your typical light duty off the shelf dry bag. Originally ordered the large and when it arrived realized how huge it was. Purchased the small as well which was more the size I was looking for. For reference, you can zip the small one on and fit two batwings and a spike duffel inside it. The large size is big enough to fit my entire F1 inside of it even with the batwings and spike duffel attached. A plus if you are wanting to keep your straps and hip belt dry and still toss in the bed of a pickup regardless of weather. Kept the large for that reason alone.
So far this is a great addition to my J34 Just One pack. Provides some modularity and flexibility for load out considerations. I haven't had the chance to put it through all the paces yet, but so far a sound investment for future outdoor fun.
Very large and durable. I haven’t got the backpack system to go with it but I plan on getting it.
Zips on easy lots of room and stays dry used it twice in the snow/rain kept everything dry and had tons of room for extra cold day gear.
This is what I've been needing, haven't used it yet but can't wait until spring time, it's too cold right now, and it hooks up to my mainframe real good so I'm happy with that, I would recommend this bag, very nice one.
Great concept - love it - looking forward to using it this spring - keep up the great work on cool ideas - JJ
Awesome. I can literally fit my 5 yr old in the bag! Literally!
Havent used it yet but beyond excited considering the long range backpacking trips I’ve already done with the frame and my previous dry bag from another company that ive been using, which is much smaller. This eberlestock dry bag is massive and will fit all my gear. Just the way the frame was designed
