Just got back from a 3 day weekend and every night was below 30 degrees. I was warm all three nights and thought the bag did well in that regards. I thought 30F rating was fair but I tend to be a "warm" person so I cannot speak for people who get cold easily. I think that for the normal person, do like they say and get a bag rated 10-15 degrees cooler than what you actually want.
The only con I had was a little bit of trouble getting the zipper to work well up near the hood. seemed like it worked fine for 90% of the zipper length but the last 10% got stuck every time. I don't know if this problem is only on my bag but it was frustrating. Maybe this is a common issue across all bags.
Overall, I thought the bag was warm, light and had most of the usual marmot quality I expect.
