Keep in mind that bag ratings assume you're sleeping in a tent and (I think) wearing a base layer, so you're right to be looking for a somewhat warmer bag than the coldest temperatures you expect.

What about rain? Don't you at least have to carry a tarp or bivy sack?

Thanks for the replys!
If I see one, what should I check? I cant really tell in a store how warm it is...
What is an overall loft?
The rating assume that you're wearing a base layer (which I always wear), but not a tent.
I do sleep in a tarp when its raining, but I dont want to carry it every hike...
