Looking at various ways not to spend a small fortune but lighten up, especially after getting an Exos 58 and Kilo 1P a year or two ago. At any rate, it looks like REI has a new bag that's about 25 oz. I checked it out at the store the other day and it looks pretty cool, if not a bit gimmicky. I figure with REI's discount, it could be gotten at a pretty decent price, though I recognize there are lighter and more expensive options out there. Any thoughts out there on this bag? Would it be better to just spend a "few" extra bucks and go with Marmot (been using the heavier Helium–awesome bag!–for five years or so) or Western Mountaineering?
Also, for those of you who use an Osprey Hornet, how difficult is it to fit a bear canister in it? Looking at this as an option too.
