    • Versatile durable pack frame
Color: Skye Size: Regular
We love this pack frame. It is super comfortable even when packing a heavy load. My husband would steal it any time he had the chance until I bought him his own!! There are only a handful of accessories that pair directly with it, but you can strap just about anything to this even if it isn’t the designated accessories. I love the batwing bags for day trips and have a larger 40L pack for overnight trips. ... show more

    • Very versatile pack frame!
Color: Military Green Size: Regular
This pack carries very well. I'm 62, 6' at 173 lbs and mostly hike and backpack solo. This pack allows me to tailor my load to the type of excursion and season. The strap system allows me to secure any type of load in any configuration I need. As an external frame it provides excellent structure to the load with a slight cost of extra weight. I uses a 41 quart Rubbermaid industrial waste basket as my main pack basket and carry my sleep system in a 30 liter dry bag at the base of the load. In camp I can take all that off and haul whatever needs hauling. I can also empty the basket and use it to fetch kindling and/or water as needed. I purchased a 20 liter pack cover at REI which is held down with 1" web lashings to cover the basket and protect the contents. I'm very pleased with this pack. One recommendation I have is to purchase the extension straps in case one needs to carry something with a bit more girth (perhaps a 50 liter dry bag in winter?) ... show more

    • Worth the money!
Color: Mountain Size: Tall
Awesome pack. Been looking at this for awhile, finally decided to get it and haven't been disappointed. Set it up for whatever you need.

    • Small but great feel
Color: Dry Earth Size: Regular
I bought this to replace another metal frame pack and feel in love with it. It's a little hard adding things that aren't part of the system but amazing all around.

    • Insanely Versatile and Well Built
Color: Dry Earth Size: Regular
I didn't think Eberlestock could possible beat their flagship J107 bag... but they did. First, it goes without saying, the quality of this pack is true to the Eberlestock name. It will last my lifetime and my kids. Second, there are just so many options for this pack. As others have said, it works well with a duffel. But I'm actually rolling with the Transformer on it and really like it. The combo is lightweight and offers great range of motion, but when I need to haul something large, I just pop off the Transformer and have a universal carrier. This is a great hunting pack but in the off-season I have it packed as my bug-out bag. ... show more

    • Great pack that's worth the price
Color: Skye Size: Regular
I use this pack to get my cardio workout. I have 50 lbs of weight on it and it holds the weight easily and is comfortable to wear. On my old pack, the shoulder straps dug into my shoulders and cut off my circulation, so I got a numb, tingly "needles" feeling in my fingers. With this pack, the weight is distributed more on the hips and so I can comfortably hike with more weight for longer distances. The narrow frame is also good b/c it doesn't restrict my arm movements and I don't feel the pack on my back that much. ~ JT ... show more

    • Big $, big quality.
Color: Mountain Size: Tall
I am over $600 into this pack counting accessories, and you probably will be too. No regrets. I fully expect this thing to last a lifetime of hunting, but the mainframe is a gateway drug. Buy responsibly :)
