Here is seven of my eight. Right to left in approximate amount of use.
1) Kelty Redwing 2900. 11 years old, it fits like a favorite old pair of slippers and I know which pocket I have put gear in, so I can always find it quickly. extremely versitile.
2) Golight Dawn. Very light.
3) Swiss gear. Piece of junk that I got free when I bought the watch. I don't care if it gets paint on it, or holes in it so I use it for trail maintenence.
4) Mammut Snowstorm 40. Nice pack, but more for snowboarders that I got on clearance but don't use much.
5) Salomon Snowboarders pack. Don't use, relatively light but only one additional pocket.
6) Osprey Argon 85. Got it for Rainer, Good pack, very comfortable, but empty it weighs over 7 lbs..
7) EMS 3000. Too small, again got it on clearance.
8) Camelback (not in picture). Use it frequently for cycling.
