I'm prepairing for a trip to far off Yosemite(1st time), a general car camping high school group maybe with a escape to the backcountry for a night or so...I'm wondering if I should rely totally on an east german surplus blanket and then do without a sleeping bag. Is this wise? I sleep with it everynight and have slept in the yard with it in maryland's spring with no complaints, and I prefer the feel and breathablity of wool to the bag. I'm just timid.
then should I get a summer weight blanket, or will wool in general ( not the heaviest blanket, but is a tighter weave, a factor in isulation) keep cool enough throughout the night? I am the most ignorant yet aspirant beginner; does anyone have any experience with wool on the trail? thanks.
p.s. this is my first post.
