I have an Eberlestock X-1. I got it mainly for use as a daypack. I used it this fall and was able to pack out a whitetail doe in it. I would like to do some backpacking, maybe a backpack hunt. I believe I could pack a light spikecamp in it with some gear strapped on outside. I could use the mesh birdbag to expand capacity or to pack meat. Is there a way to attach the spike duffel to an X-1? This would be the most economical way to expand the X-1 for use in limited backpacking rolls. The J-34 would obviously be a better choice and is marketed as useful cinched down as a daypack. Is the J-34 truly useful as a daypack or is it gross overkill in that roll?
