Hi Alsatian:

This is the bag I use for exactly the situation you described: I also noticed the price is now 50% OFF!!!!!!!!!!!! I might have to get an extra one...

I use it for pack in hunts. The bag is not very heavy, but bulky. I use a 5500 cu in pack, and have always had to lash it to the frame.

Good Luck.
