Likely to be used inside my hammock at night...lightest woul be???
Look at MB, Pata, MH, Rab, Golite, ID, Arcteryx in the non hunting world. They all make good stuff and have lightweight options, but sometimes a challenge to find earth tones.
I think Kuiu is the only hunting company that makes a truly lightweight puffy.
I currently run a MB Thermawrap synthetic for milder hunts (8ozs), a MB Alpine Light down parka for when it's cold (14oz), but just added a FL Uncompahgre as well which I like a lot, but it's heavier at around 19ozs.
