Anthracite 20°

You don't buy a Coleman sleeping bag. There are plenty of bags out there, even inexpensive ones, that are warm and pack down small. [This one](https://www.rei.com/product/216102/big-agnes-anthracite-20-sleeping-bag-mens) compresses down to 7.4L and is $105. That's fork bag size.

This is a solid bag. My Scouts have it and like it.

It was the Big Anges Anthracite 20° synthetic sleeping bag. Not currently on sale but I think it's still great value.

I will test my Anthracite 20 this weekend, temps are predicted to go down to 32, so right on the comfort rating. Will report how it went! I got it new for just 70€, if this thing works well at that temp it was well invested money!

Happy to report it went really well. Temps went not as far down as predicted, "only" down to 36F, but I was pretty toasty, couldnt even close the hood , otherwise it was too warm for me. Used a R4.2 sleeping pad and was wearing long base layers as well as Merino wool socks and hat. Very confident this would keep me warm even down to 32 or a few degrees below.

Have a Big Agnes 20 and a Magma 20. Both down both compress well. A few years ago, I switched to those liners in the summer and love them. Warm enough in July. Pack extremely small.

I would go with a quilt, they are great for moving around. Zenbivy is most peoples favorite, I really enjoy my Big Agnes.

If your biggest concern about a sleeping bag is room for your legs to move without feeling constricted, I would try out Nemo or Big Agnes sleeping bags. Both tend to have wider profiles. Definitely go for a bag that is rated at least 10 degrees lower - preferably lower - than the temps you expect to sleep in. Theres multiple problems with layering with clothing like this, one of which is not the warmth specific factor but the breathability. One or two layers is one thing, but with all the listed clothing and then something like the picture on top, you’re going to build up humidity near your body you can’t get rid of, and you’ll become even colder. Next, a sleeping bag basically creates a warm pocket of air around you. The insulation in the bag helps create and maintain this pocket. The more compressed this insulation, the worse it performs. With layering clothing, you compress the insulation, making it less effective. On top of that, insulation is minimal if not nonexistent at the seams. Some puffy jackets and “extreme temp” clothing gets around this by minimizing seams but there’s almost always a few somewhere, which means no air pockets and no warmth. If I could recommend the best case scenario for you, it would be this: find a sleeping bag you can tolerate rated to a temp appropriate for your conditions, 15F at a minimum, best scenario a 0F. Dress in only your smartwool layers, and make sure you have a good pad/sleep set up underneath you.

A Big Agnes sleeping bag with down that fit me correctly. I was iffy on the price at first, but it turns out I had basically used ill fitting, non insulated sleeping bags for years of wilderness camping. Getting a good nights sleep anywhere, especially away from home, makes a huge difference.
