In every review I try to find good things and bad things to say. I had a hell of a time coming up with anything bad to say about this sleeping bag.
I am a very cold sleeper. I've tried all the tricks: eating prior to sleep, hot water bottles in the footbox, layering, blah blah blah. I just sleep cold. I have never been anything but toasty warm in this sleeping bag.
The Z-10 is somewhat constricting for me, but I'm a sprawler and a thrasher. If it wasn't moderately constricting it'd lose insulation value so I can't really knock it for this as it's a personal thing.
With its full-length double zipper, the Z-10 is very easy to get into and out of.
The Z-10 has a pertex shell. Don't worry about sneezing on it. It's also a down bag. For the love of god, keep it out of that creek.
The only bad thing I have to say about this bag is that it's a bit of a pain to stuff into the provided stuffsack. It can be done, but it lofts so well it can be a struggle to get it all in there. However, if this is a major selling point for you, I'd recommend giving up backpacking and spending your time playing pinochle.
The zipper rocks. It's simple, effective, and doesn't easily snag. It's also a double zipper so you can create a vent hole all along the side of the bag if you get too warm. I never get too warm, though it's nice to know the option exists. You can also unzip the entire bag and use it as a quilt, though at 3 lbs, that is one seriously heavy quilt.
This is a new product so I can't really comment on durability, though the bag seems very well constructed.
It's cheap. For an 800 fill -10 degree rated bag, $400 is a steal.
I've used this bag during winter/spring 2013 in the Colorado mountains. I like it so much I have taken to standing on my front lawn, holding it in the air and cheering/screaming "wahoo!" at passing motorists.
