I received my brand new PeaPod III today. The specific measurements written on the tag are 19 oz down (2 oz overstuff), 38 oz total weight.
On Friday, October 23, I will embark on a 9 night test. Nighttime temps are forecast to range from below freezing to high 40's. I'll use the PeaPod with my Speer 8.5A hammock, underneath either a Guide Gear camo tarp or a Speer Winter Tarp.
I'll let you know how it goes!
