Cedar Ridge Birch Creek 20-Degree Sleeping Bag

I've used this bag several times, and I've not been cold yet. Based on how close I've been to cold, though, and my own experience with other bags over many years of camping and backpacking, I'd say this bag is a solid 30deg bag, and might even go down as far as 25-28deg, depending on how warm you sleep. I tend to be right in line with the EN ratings for bags I own (even on a couple where I didn't know the EN until after I'd slept out in them and found the lower edge of comfort), and I've slept well in a bag rated to 17deg via the EN system, down to about 15deg. At 14deg, I was mildly cold in that bag. So I'm estimating this bag is solid for 30deg, and maybe for 25-28, based on my prior experience. It is light, at just under 3lbs, but when you add the compression sack, it goes over by a few ounces. Also, best compression gets it down just smaller than a regulation basketball, so it's not small in your pack, but not huge, either. A different style of compression sack might be better for making it fit into some pack styles (less "round" and more elongated).Overall, this is a good bag for the price, and I recommend it to my Scouts as a first backpacking bag, as it's comfortable down to most of the temps in which we backpack here in the southeastern US. Once a Scout has their basic backpack kit together, I always recommend adding a colder bag (something legitimately between 0-20deg) so when we camp in Jan/Feb they're warm enough, but if you're just looking for a comfortable night's sleep at 30deg, this one will do the trick.Bear in mind, though, that the EN system to which I refer above is a standard which includes a good pad beneath you (R-value in the 3-5 range) and assumes you'll sleep in a base layer with socks and possibly a skull cap. That's how I sleep when it's cold out, and that's how this bag rates a solid 30, maybe 25-28 for me. Go in a t-shirt and boxers, and you're going to lose 5-10deg of the bag's capability. Conversely, add a heavy fleece bag liner and you might make it to somewhere between 15-20deg, in this bag, with a baselayer.Hope that's helpful.Edit: Apparently the price on this bag has doubled, and it's no longer the bargain it used to be. I'd steer clear of it anywhere north of $45. There are much better options out there in the $60-100 range.

Not sure how long the compression sack will last, but this sleeping bag served me well in 30 degree weather with 20 mph winds. I was layered up and sharing a tent, so I probably wouldn't have been very comfortable in the sleeping bag if I had tried to either sleep without shelter or lightly clothed.If you're an occasional backpacker, this should fit the bill.
