- Familiarity: I've used it once or twice and have initial impressions
So this is my first 0/1 degree bag, so it's hard for me to compare performance completely. But here's the gist:
I got this to do a winter camp in Rocky Mountain National Park. Estes Park, at a lower elevation, had temps into the low teens during that weekend. My campsite was very windy (selected for the view, not warmth), and my cheap thermometer seemed to indicate it was around 10 degrees in the 3 season tent, so perhaps lower outside.
I was chilly, but mainly because I was sleeping on snow and only had 1 sleeping pad. Threw a nalgene of warm water into my sleeping bag each night.
Seemed warm enough, but I typically sleep cold and am okay with not feeling my toes.
As far as features:
The zipper did snag a couple of times, but otherwise worked very smoothly. The hood cinched down well, and it was roomy enough inside the bag (a lot of 0 degree bags seem to have less space in order to save weight and warmth). 5'9" and 170 lb seemed to fit the regular great.
I definitely will take this out again for weather less than 0 degrees. I'm going to get a temperature logging device so I can see how it performs at different temperatures.
