          F1 Mainframe backpack.

          I recently purchased my second Eberlestock F1 backpack. This is a frame that was designed for packing out animals in hard to reach areas ( Like the side of mountains.) The frame is lightweight, quite and most importantly comfortable to wear. The mainframe is versatile with 2 heavy duty zippers that afford me the option of easily attaching my batwings, duffle bag or transformer frameless pack to it. I place the deboned meat inside of my wet bag and set the bag on the shelf securing it with the 3 snap buckle straps. This method keeps my clothing dry and blood free while still keeping my Gore-Tex with me incase a storm blows in. I make several trips carrying out only 30lbs. to 40lbs. of deboned meat per trip because it is safer. The backpack opened up hard to hunt terrain where fewer hunters go and the big game hides due to less hunting pressure. The second mainframe is a birthday gift for my son. Buy your loved ones the gifts they really need to succeed and watch the smiles on their faces. - Todd Spence

          Fits great

          It fits me great and I’m a large guy (6’4”,300). I’ve had issues with packs in the past not sitting correctly on my shoulders and hips. I haven’t tried it out yet but hopefully I’ll be packing some elk this coming October.

          Excellent product

          No question great quality. Using it elk hunting archery Mount Saint Helens. Little disappointed my son ordered the same product and received a hat and 3 coozy holders. Again wonderful gear!

          Easiest shelf system and super comfortable

          I purchased the F1 with two batwings after extensive research on pack-out packs. Mainly based on how easy it is to load the meat up and get moving. Other systems require to much zipping and rearranging and seem to complicated. This is easy and can carry a lot of weight. Fitting it me was straight forward using the videos and the construction is top notch. Love that it’s modular and you can conform it to your needs. Also as a bowhunter I am completely comfortable drawing with the pack on because it is narrow and stays close to the body.

          Holds lots of weight comfortably, like how customizable it is.

          F1 Mainframe w/ Vapor 5000 or Batwings

          Excellent. I have taken this on two trips one overnight and one day hike. The frame is comfortable and provides a more rigid feeling during the hike compared to packs previously used. Highly recommend.

          Vapor 5000

          I bought the 7500 first. It was to big so I got the 5000 and i love it its great. Only thing I would change is two extra straps and putting the badder holder in the center against the main frame
