This is for 2 people yes? Big Agnes King Solomon 20 degree + Big Agnes Rapide SL tent floor pad (the one that’s 78” x 50”). And you add an ultralight quilt and/or individual bag liners to the system when temps are actually 20. I sleep colder than my partner so I’m the one who adds a down quilt — he is comfortable in a 20 degree bag at 20 degrees; I am not, even when we’re sharing.

I just went through and looked at double sleeping bags. I just bought the King Solomon 20F. I do some car camping but wanted something lightweight for backpacking and it was less than 4 lbs. I found it on sale for $375. I’ve only spent two nights in it but so far I’m happy. Some of the other sleeping bags were 8 or 9 lbs and that was significantly heavier than I wanted to carry.

It does. My wife is generally a side sleeper and I thrash around a lot and we found it roomy enough. It doesn’t have any insulation on the underside. It relies on your ground pad to provide the insulation. I was a little concerned about that aspect but it worked great. Your ground pad “connects” to the sleeping bag to keep it from sliding off. I will be using it on a 20F and a colder night just to see how it performs. Big Agnes lists it for $499 on their website. That’s a lot of money and I doubt I would have paid that much. I searched on eBay and found a couple of new ones in the original packaging for $375.

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.

Just wanna say I respect the lack of overpriced fancy gear and I respect making it work for as long as you did! As much as I am “anti gear, pro getting out there”, a lightweight Big Agnes sleeping bag will roll up to about 1/8th the size of a rolled up Coleman. Mine has lasted me for 7 seasons so far no problems
