The only thing waking you up with be the northern lights.
You're visiting Alaska in September because you came for the autumn foliage, the blueberry bushes turned magenta, the golden aspen, the blood red leaves of bear berry. You came for the midnight show. You also know you might wake up to frost in the morning. That's quite alright because the Sierra Designs Nitro UL 800 DriDown 0 Degree Sleeping Bag will give you a good night's rest, keeping you warm even if the muskeg gets your gear a little wet.
Packed with lofty down, the soft folds of the Nitro UL 800 offer comfy levels of warmth at temperatures well below freezing. The bag is lightweight for long trips into the Alaskan wilderness, and it packs down small. The Dridown doesn't mind if things get damp—treated by Sierra Designs to be hydrophobic, these feathers keep you warm rain or shine.
A five-inch baffle design also means those feathers aren't moving around as much, keeping you warmer. If things do get a little stuffy at night, you can just bend your knees and the foot vent pops open, letting in a cool draft. When your partner wakes you up at two in the morning because there's a wild aurora borealis display, the anti-snag zipper tracks means you can be out of bed in a jiffy, and back in just as easily.

- Q & A
10 Nights in the Nitro 800
- Familiarity: I've used it several times
I was given this product from Backcountry, but this review Is my personal opinion.
The Nitro 800 has a flashy name, but the bag itself isn't anything flashy. There's no bells and whistles. That being said, there are some pluses and minuses I experienced in my 10 nights using this bag on Mt. Baker, Constance, Anderson, etc. Those conditions were during 10-20 degree nights.
On the plus side, the price of this bag isn't unreasonable for what you get. It's a 0 degree, down bag that weighs 2 pounds 8 ounces (for the regular bag). The warmth and loft on the bag, while not exceptional, was middle of the pack in comparison to other bags I've used. That being said, the bag was somewhat bulky and didn't pack down as well. The one part of the bag I really didn't like was the foot vent. This is a ~foot wide hole in the toe space of the sleeping bag. There is no way to close it off; although there is an overlap of material that blocks the area from free flowing air, but it's easy to slip your feet out this space if you're rolling around like I do, especially in cold weather when I'm sleeping on snow. That being said, if you sleep warm or cold and need ventilation, then this bag is for you.
One other downside for me, and if you're a couple, is the lack of a full zipper on the sleeping bag. Venting for me is often made by just sleeping on the sleeping pad and draping the sleeping bag over me, fully unzipped. That isn't an option with this bag.
For me, the Nitro 800 was a great bag in weight and warmth, but lacked in overall quality of zippers and extras, such as a compression sack or a large storage bag. Moreover, the open vent in the foot well was not something I could appreciate, as my feet are usually the coldest part of my body.
