Sleeping bag for back country?

[Kevin Root]

I wonder if that would work well enough for the early season as your only shelter.

I have not checked the product out yet in person. So, I'm not sure how durable it really is. They describe it as a lightweight emergency bivy, but if you protected it from the ground abrasion it should be ok I'd gather from the clip and what I read. Some of the SOL products are really meant for emergency and kind of delicate like the space blanket but this should be a lot more durable than that.
