I own a GG Nimbus Ozone (3#) for hiking with my kids and winter hiking. I love it.
I stopped by a rarely visited outfitter's today and noticed they had 4-6 GG Nimbus Ozones (didn't check size, etc.) for $119. That's a steal.
Here is the store...
They make their money from selling RV's and don't spend a lot of time/effort with the "upstairs". So, don't expect an answer everytime you call the backpacking number.
