Re: Which Eberlestock.?
to the OP, "Which Eberlestock" depends on what you are planning to do...
If you are looking for one pack for everything, day pack, week long back pack hunt, hauling out 100lb loads of meat, the J107/J34 will meet your needs. If you are only planning day trips, will hunt out of a camp every day, maybe have access to other packs, (or friends with packs) you might want to look at one of the lighter packs like the X2 or X3.
I bought a J107 as my first "do everything" pack... But it weighs almost 9 lbs empty. Add in an 11 lb rifle and you have a 20 lb pack without any kit.
So, I bought a slightly used X2 as a day pack to compliment the J107. If I am planning an all day outing, potential to bivy over night, the big pack goes. IF it will be a quick trip, scouting, etc, the lighter pack goes.
If you are long, tall, short, thin, wide, you might want to make sure you get one of the Eberlestock packs with the replaceable hip belts and shoulder harness. Then you can customize the pack to fit you. I put an XL hip belt on both of my packs. The standard belt fits O.K. with summer clothes. But would not fit over my cold weather clothes. Plus the additional padding on the XL belt makes it even more comfortable. I am currently doing 1.8 miles around the farm 2x per week with total pack weight of 60 lbs in the J107. The pack itself is still very comfortable for me. Will work up to 3+ miles 3x per week before I leave for Colorado in October.
