      THE HOLY GRAIL OF

      MODULAR PACK SYSTEMS

      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

          Flawless Hunting/ Camping Pack

          I bought the mainframe and Vapor 5000 and it is super comfortable and there is a ton of space inside. The quality is great and it looks amazing too. There are so many design features that will be very useful in any wilderness expedition. Thanks so much Eberlestock for the great products!

          An Absolute Game Changer

          The design of this frame and the different configurations intrigued me. I decided to give it a shot and that was the best decision I've ever made. The lumbar support on the harness is insane and makes weight easy to carry. Great support going through your back as well and good ventilation in the back. I really like the webbing on the hip belt as well, it makes it easy to attach a small accessory pouch, medic pouch for quick access or even mount a handgun. I picked up the Vapor 5000 with it and a Batwing shortly after. I love how within 2 minutes I can completely refigure my pack for a back country hunt or just a day trip to do some scouting. Due to the versatility and great design, I think this is a frame every hunter / backpacker should be running.

          A+ for quality and fit.

          Ordered mine with the batwings. Love the way it fits my already owned day bag with the addition of the batwing storage. Pretty excited to put it to work this fall.

          Mainframe is comfortable and robust

          I have worn it with a pack a few times and hiked up and down a hill in training for a longer trek. It is very comfortable, adjustable, and distributes weight nicely around my waste, putting little pressure on my shoulders. So far so good! I’m happy I bought it with the EMOD 5000.

          MAINFRAME & VAPOR 5000

          I purchased the mainframe and vapor 5000 with the intention of it replacing my current camping backpack. I am very happy with my product. Eberlestock delivered the products earlier than expected and in good condition. I am super happy with the products and the materials they are made from. I only wish the products shipped with instructions on how the EMOD system pieces together, or I wish there were instructional videos on the website. Otherwise great products, I am happy with my purchase.
