Sleeping in a winter sleeping bag on snow in Alaska in January, a camper is tucked up and bundled up tight in his down sleeping bag. Mountain Hardwear Ghost sleeping bag, Exped Sim Comfort 10 LW.

It’s January, and Alaska can be a rough place to sleep outside during this time of year. Temperatures can easily be down below zero F, even into the minus 30′s and 40′s, or colder. So sleeping outside is not to be taken lightly.
Bring a good sleeping bag. A REALLY good sleeping bag. If you predict temperatures of zero (F), I’d go with a sleeping bag rated to minus 20 degrees F. I prefer a down sleeping bag over synthetic bags, but the key is a high quality, and well rated bag. If you have a good synthetic fill sleeping bag, use that. It’ll be heavier, and less compatible, but you can deal with that. You don’t want to have to deal with being cold.
Your bag is your last refuge against the cold. Don’t skimp on it. Bring “more” sleeping bag than you think you need. I do like the goretex or similar shells for winter bags, and highly recommend them.
Bring a good sleeping pad. A REALLY good sleeping pad. Jake, above, is using (well, half using) an Exped Sim Comfort 10 LW, which I highly recommend if you’re not packing it into the backcountry. If you need to haul it (snowshoeing, skiing, backpacking, go with an Exped Downmat 7 or even the Downmat 9). An insulated pad insulates you against the cold snow underneath, where even the best sleeping bag won’t offer much protection – once you lie down in the bag and compress the insulation underneath you (be it down or synthetic), it offers little insulating value. So a high quality insulated pad makes a huge difference. You want it to be about an inch or more thick.
Although it’s not generally needed with a high quality sleeping pad like this, I often like to throw a hard cell foam pad under the inflatable. It adds a little extra insulation, but mostly a little protection against a leak or anything. It’ll definitely ad to the life of your sleeping pad. Unlike Jake, above, don’t slide off the sleeping pad. You’ll get cold.
