These are so comfortable and you can tell these are a very durable, long haul investment, which was actually my primary motivation. But whether out in the cold or inside, they seem to manage to keep a good temperature.
My only complaint regarded service. I ordered these while away, so where it asked for delivery instructions, I specified to please leave the package on my back deck. I didn't want a package sitting on my front steps during the holidays announcing to anyone who's looking, "Hey, nobody's home!", and sure enough, they were left on my front steps.
Great product though!
