Mainframe

I am 6'-3" and purchased the tall pack. In hindsight, I should've gone with the standard frame but on the shortest setting it works well. That said, the pack is super lightweight and comfortable. Can't wait to use in on my deer hunt next month!

Extremely impressed. I’ve been running the F1 mainframe paired with 2 batwings for a couple years now and have zero complaints. I primarily use this setup for day hunting whitetails in the Appalachian mountains where packing out game is the only reasonable option. But have also used it for 3+ day hunts. The pack is light enough for early season day hunts but also capable of late season multiple day hunts where more clothing layers and extra gear is needed. It’s the perfect pack for all season and can handle anything you throw at it. From ground hunting to saddle or hang on stand style hunting, the mainframe is perfect for any scenario. Endless modularity options to customize your pack the way you want it is a major upside. The whole system of packs and accessories in this line are top notch. Eberlestock is a step above the competition with this pack and its options.

I have not hunted with the pack yet, but I have done a few training hikes with varying amounts of weight in the pack (15-90 pounds). So far I am very impressed! I have it paired with a Vapour 5000 which I also really like so far.

Another quality product from Eberlestock as the frame is well constructed and light weight. Has many anchor points and included cinch straps to make sure any load carried is stable secure. Many optional accessories will likely make this a favorite hunting pack!

Great light weight sturdy frame with 100X combinations. Fitment is awesome and carries loads very well!! Great price point. You can get carried away with all the options but that a good thing!! 10 out of 10!!

Awesome. So many options with this setup. It Definitely can hold more than you can carry.

Fits good because it has adjustable shoulder harness and padded waist belt. Both batwing fit good.
