Blanket for backpacking? on 09/28/2006 09:20:17 MDT Print View

At what temperature can I sleep comfortably with just a blanket? I'm planning a 3 day trip and I might see overnight temps drop as low as 40 degrees farenheit. I could drop a few pounds by leaving my sleeping bag at home and just carrying a blanket, but I don't want to be miserable, though at 40 degrees, I'd hardly freeze to death. Has anyone done this? How did it work out?

Thanks.

I've taken fleece blankets when over night lows were no less than 55-60 F. They don't save any weight over a much warmer down or synthetic quilt with a loft of an inch or so, but are much easier to keep from overheating. But below 55 it seems insulation needs go up non-linearly. 1 inch top loft seems to be comfortable in the 45-50 range, and at 40 1.5 inches is probably about right. This is without other insulation. Your needs may vary. If you are a warm sleeper you might get by with less, but 40 F is definitely in the realm of hypothermia as soon as any wind or dampness comes into play. Also, don't forget head insulation.

I've slept under nothing but a 300 weight fleece blanket in summer and fall in the Pacific NW. I wouldn't recommend it, as most camping blankets are short a tad (I'm 6'0"), they aren't windproof (I sleep under a tarp), and they aren't that light.

Fleece blankets are warm, light, and comfortable, and I really enjoy the freedom of a blanket over a bag. But, there are better choices. I've since obtained an Integral Designs Prima Blanket, which is (off the top of my head) rated at about 50F, is 1-inch thick, is 28 oz, is filled with water-resistant Primaloft, is shelled (on the outside) with water-resistant Pertex, and, thanks to the zip-out hole in the middle, doubles as an insulated poncho. It's also black which facilitates drying in the morning sun. With a 5-oz rectangular silk liner bag (so I don't have to sleep directly on my sleeping pad) I'm comfy down to 45F.

This year I obtained a Jacks R Better Biker Quilt when I saw some offered at a great price. It's a 24-oz down blanket that's 1.5-inches thick. With the silk liner I've a comfortable 29-oz system good to 40F.

Both the Prima Blanket and Biker Quilt convert to bags if one opts for such a configuration. This option is nice for making a foot box when the temperatures are low enough to want to keep my radiating feet covered. These are both a lot pricier than a camping blanket, but I've found them to be worthwhile purchases.

My son has a poly-filled Fanatic Fringe quilt rated to 30F--very light and lots of loft, but it has a fixed and rather small footbox, which I find too confining.
