Aircore Blanket (courtesy, Lands’ End)

Do you have a question of your own?

Well, Josh, I have to be honest: I don’t even begin to agree with your premise. True, there is the historical model of the bedroll, which of course helped “win” the West…or at least helped rob it from the folks who were already there. But I can’t even imagine trying to use a blanket for anything halfway serious.

Let’s look at an example. I’m going camping where I expect to see low temperatures of around 35 degrees. Chilly, but not real cold. I could, per your theory, pack along something like a Lands' End Aircore Blanket ($45), which is made with Polartec 200 and is a nice warm blanket. Now, I happen to have one of these, and it tips the scales at about 15 ounces. And I would need at least two of them. So we’re close to two pounds.

Meanwhile, my MontBell U.L. SS Down Hugger #3, rated to 30 degrees, weighs one pound, seven ounces. That’s seven ounces less than the two blankets. Plus it’s warmer because the Polartec pieces aren’t that windproof, and the sleeping bag is much more resistant to drafts coming up from the floor. One could shave some weight off the blankets by trimming them down to a more oval shape, but then you lose the ability to tuck the edges under yourself. The bag does cost $260, but for its vastly greater performance, I don’t think that’s bad.

If someone has numbers that make more sense than this, send them on. Otherwise, I’m sticking with a sleeping bag.
