So I find myself probing you guys for all sorts of info, not just lightweight stuff, because I don't think theres another forum with as much knowledge as there is to be found here. Now that I've sucked up the proper amount, my question.
Been looking at Feathered Friends 35 deg. Rock Wren http://www.featheredfriends.com/Picasso/Bags/Specialty.html A long weighs in at 29 oz. For those not familiar, the Rock Wren converts from a sleeping bag into a parka of sorts via two arm holes and a cinchable bottom. Gone would be cold mornings shivering while eating breakfast! I'm hoping the ventilation for summer heat would be as good as a full zip bag (which this is not) because you could sleep with your feet and arms out of the bag. I plan on using this bag for everything from Northern New Jersey to the high country of Wyoming, increasing my clothing as it gets colder.
Thoughts, warnings, etc? I may ask for 2 oz of overfill, heard theyll do that and other custom trick outs. I've read that this company's temp ratings are actually quite on, but just in case, I may opt for the tiny bit of overfill (they use 850+ down).
