The biggest bang for the buck I have found is to put a thin foam mat under my Big Agnes inflatable. Apparently my insulated inflatable isn’t that good. Adding a cheap foam mat adds 10–15 degrees easy. I am good to 25 degs now with my current gear. Thanks for the article. I am trying to extend my adventure riding season and getting more comfortable with sleeping outside in December is a big deal.
another or as an extra option is a mylar blanket, they pack down to nothing and weight nothing and cost about $3-5, I had one between my sleeping bag and mat and it made a significant difference...but noisy!
New Zealand has 2 winter motorcycle rallies, the Cold Kiwi in the North Island and the Brass Monkey in the South Island. I've done both and the temperature varies each year but the last few years I went to the Cold Kiwi it was usually around -8 Celsius at night which I think is about 17f.
I use an Exped Downmat for my bed which has a R rating of 8 and takes up about half a saddle bag. @rtwPaul I also use an emergency thermal mylar blanket on the ground under my bed, it still seems to work and is much quieter.
Having a good under layer made much more of a difference than putting on more top layers.
For the sleeping bag I can't remember the brand but it's rated to something like -4 or -6C, but it rolls up huge, however given I am just on a weekend trip and not travelling RTW it's not a huge issue to throw it in a dry bag over the rear seat. Unfortunately my budget doesn't extend to $1400 for a sleeping bag.
Combine those with wearing my thermals and a woolly hat to bed with a hot water bottle and I'm usually fairly cosy, the couple of bourbons around the bonfire probably help too.
Don't breath into your sleeping bag thinking you will warm it up, the moisture can freeze and make you colder.
