Watch the in-depth pack overview video below.

The F1 Mainframe represents what is arguably the greatest innovation in modern pack making, the holy grail of a great modular pack system. But unlike any other pack system, with this load bearing workhorse as a base, you can build a true ultra-light pack simply by adding one of our J2DB Dry Bags.

The F1 is one of the primary base-platforms for the EMOD -- the  Eberlestock Modular System, and it works with an ever-growing number of complimentary accessories. Add components of your choice, and the Mainframe can function as a freight pack, day pack, or all-around utility pack.  For hunting, it transforms to a meat hauler within seconds

Perfect Pack for Elk Hunting

I have used several packs over the last 15 years hunting elk in the montana back country and this is by far the best and most durable pack. It is very strong and you can tell nothing is moving around in the pack while carrying a heavy load.

Amazingly Versatile

We have several Eberlestock packs but the F1 Mainframe is by far my favorite. With the option to zip so many different attachment packs, this is the ultimate custom pack. With an unlimited amount of combinations you can build anything from a minimalist single day pack ready to carry any kill out to a multiday back country carry all hunting pack. If you dont have one buy one!!!
