watershed vs prijon
I'm with 'Deep South' on this, I had the Prijon bags for a couple of years and they started leaking after about five self-support adventures... So for me the futas ended up being a better value in the long run. I'm fortunate to live where winter self-support runs are possible and a wet sleeping bag and lows in the 20's would make for a miserable night at best.
I also have his exact set-up with the addition of a 2quart NRS roll-up bag I pack just behind the seat with lunch in it.
Futas are bulky and can be a PITA to shove behind the seat (at least in my Nomad) to alleviate some of the pushing I've carved out a bit of the rear bulkhead foam, no more than a inch but it helped.
