Eberlestock - Mainframe Frame - Tall - Mountain - F1THM:

The F1 Mainframe represents what is arguably the greatest innovation in modern pack making, the holy grail of a great modular pack system. It will haul any man-portable load with the same alacrity and a lot more comfort (and quiet) than a giant freighter frame. 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 Eberlestocks J2DB Dry Bags. Underlying this is the reality that you will have a great deal more capability than with any other lightweight system. Alternatively, combine it with an Eberlestock duffel, dry bags, or zip-on packs to build the style of pack that you need. With the Mainframe you can build what the mission of the day calls for - so you can always have the right gear, right when you need it.

The Eberlestock modular system works with an ever-growing number of add-on accessories. The Mainframe can function as a freight pack or a day pack, and transforms to a meat hauler within seconds. With solid NT7 or 1000-denier nylon fabric, depending on your color choice, coupled with our ultra-light Intex ll aluminum frame, the Mainframe shaves off pounds while maintaining superior strength and comfort. Stop settling for some of the above and move over to all of the above with the Eberlestock Mainframe.
