When you keep looking at the same piece of gear for over a year you know its what you really want.
I just tried on the newest version of the x2 pack by Eberlestock and wow what a pack. It has a bomber tubular frame now that just shouts out 'over load me" and provides really good ventilation across the back. This is a big deal out here in the west where it can get warm during archery season and a typical hunting day requires no small amount of physical effort.
One nice feature is that the pack will fit taller archers too. I'm 6-2 and found some packs like the Jim Horn daypacks to be short strapped and only would fit if I ordered the longer straps for about 40 bucks extra. (I don't think so).
The "wings" on the x2 open up to reveal a gigantic area where you can attach a LOT of gear or a big animal quarter. The pack is pretty simple too without a million gee gaws that just complicate things and I like that. You also don't have to use the hydration pockets for water either, another nice option/feature that makes this pack very versatile. I'd choose to use them for gear, since thats my bias and carry a filter and my water in a nalgene. These pockets are in a great location for those things you want at hand.
Anyway, if and when I get the extra cash I will be buying an x2. Glad I had to wait and will now have the new version.
