Whats a good all purpose temp rating for a sleeping bag? Is 30 deg good enough or bump up to 20 deg? It would be used from sept to late oct, and I know weather can very greatly.
Good points there also^I think a lot depends on whether you are a warm sleeper or a cold sleeper. It also depends on the quality of the bag and their rating. Some bags ratings are way off. I use a 20 degree EE Quilt, where I hunt in Wyoming. I am a warm sleeper and this seems perfect for me.
I'm gonna go out on a limb and say a 30 degree bad would not be sufficient until late October for most. If you said from Aug to late September that might be a little different. Other factors are where it's being used, if there's another heat source and if you tend to be a warm or cold sleeper like has been mentioned. I use a 0 degree bag all year long backpacking in Colorado. I'm always glad I have it as it get's cold in those mountains even in the summer overnight! I'm never to hot, and if I get warm I simply unzip the bag a little.It would be used from sept to late oct, and I know weather can very greatly.
I have a 30°+ bag that I use in the summer and a 0° bag I use when the weather starts to turn. The 30° bag I bought of craigslist for $10 and it is a retailed $200 bag. I'd say buy a nice cold one and get a spare mid weather bag like I did and your covered from warm to cold weather.Thanks for the reply's so far guys, I know its very hard to cover all basis with one level unless I just go as cold rating as possible. Price wise it will prob be in the middle/higher price range. Spend once cry once right? I'm thinking most of the time it won't the extreme cold temps that's why I was thinking the 30-20 range. I'm normally a warm sleeper seems my body is like a furnace. I could also add a fleece liner if its going to be colder. I'm looking at a good down bag that I can use from 1000-11000 feet.
