Blew $85 on a "4 season" sleeping bag rated for 15 degrees that left me shivering at 38 in Yosemite
Last October I woke up at 3am in Upper Pines shivering so hard I could barely unzip the thing, and a ranger the next morning told me most budget bags inflate their temp ratings by 20 degrees at least, so now I want to know what bags people actually trust below freezing without dropping $400.
