Big Agnes - Anvil Horn 30

Big Agnes makes some very nice 30 degree bags with air mattress and pillow holders at only 2 lbs and $200 USD. That sort of deal was unheard of just a few years ago. I can't give you a model because they change it every year. Mine is called the Anvil Horn or something like that. If you want to get under 2 lbs then plan on forking out $500 and eliminating the zipper.

Those were just examples for the criteria I listed, which may not be your actual criteria. I actually have that sleeping bag and it's fine for a side sleeper. A bit tight, but still very comfortable. I just replaced it with an Enlightened Equipment Enigma 20 degree quilt in wide size. I was able to drop a pound off of my weight doing so. That's an expensive quilt though, especially in 950 fill. You may want a square sleeping bag, or wide quilt if you're an active sleeper. You don't have to buy an inflatable pad, but they sure are comfortable. I spent years on the trail waking up stiff. After buying an inflatable mattress and pillow, I wake up feeling good. You can also get a foam pad like the Nemo Switchback, which is a lot cheaper, but not as comfortable. Your ground mat (whatever style you choose) provides insulation between you and the ground. We lose a lot of heat through the ground without a pad. The insulation value of the ground pad will be rated with something called R value. Foam pads are usually 1-2 R value. The Neo Air I suggested has an R value of 4, which is approaching late fall, early winter levels of protection from the cold.

Check out the REI outlet online. The last bag I got there was from lightweight Big Agnes, and the discount was 40%. Great backpacking bag so far!

I went rei big Agnes, but I also have 2 (20 year old) down bags that I put inside each other that can keep me just as warm and combined they are as small and light as big Agnes but with down moisture is the enemy and in winter there is plenty so there is that

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.

I got a big Agnes bag that has an extra zipper kind of like carry-on luggage. Makes it somewhat adjustable - roomy most of the time but when I really need the warmth it’s more snug.

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

I have a Big Agnes bag. It allows me more movement as the back is where the sleeping pad goes and it’s more “bed like”.

I got my Big Agnes down bag used from REI and it was cheap. It's kept me warm at 12-15f several times.
