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

  • The Transformer is ideal for day or overnight hunt trips. Stay organized but still have a frame to haul meat.

Exceptional!!!!!

Just spent 2 weeks hunting in the Cascades and I can’t say enough good things about the F1 and bat wings. Without a doubt the most comfortable pack I have ever worn. Tough as nails as well. Looking forward to purchasing add-ons to this well thought out modular system.

Comfortable and versatile pack

I highly recommend if you're in the market for a pack. Finished this frame with 2 batwing pouches, butt bucket, and the top fanny pack. Modular, useful, and lets me decide how to carry equipment specific to each trip.

The Best!!!

Absolutely by far the best frame pack ever!!! Carry anything!! It will hold more than any man can carry.... My late season set up comes in at 30 lbs. I like all the comforts of home. It feels like 20 lbs. No weird unbalanced feeling at all. It's all qhere it needs to be. I got the thick waist belt for bit and it's like a Cadilac!!!
