24oz's....ouy, that seems alot! I already carry a puffy jacket(costco) that I've never used when sleeping.....Looking back at the last outting, what bothered me the most was cold legs/feet. I like the idea of having clothing that in a pinch could also be used for cold mornings/evenings milling around camp. Fleece pants and down beeine are now on the wish list. And diy fleece booties are in the preliminary planning stage. Fairly sure these should come in at around 8 >10oz
