The F1 Mainframe will haul any man-portable load with the same alacrity and a lot more comfort (and it’s quieter) than a giant freighter frame. However, unlike any other pack system, from this load-bearing workhorse, you can build a true ultra-light pack simply by adding one of our bags, such as the F2 Transformer, F65 Little Big Top, or A6SB Batwing Pouch.
The Mainframe can function as a freight pack or a daypack and can transform to a meat hauler within seconds. With our solid NT7 or 1000-denier nylon fabric, depending on your color choice, coupled with our ultra-light Intex II aluminum frame, the Mainframe shaves off pounds while maintaining superior strength and comfort.
