I got a modular sleep system at the thrift store about $14 so I use that when it gets very cold if it's going to be 30 to 40° or more, I'll use my 20° Coleman bag just since it's lighter, but the sleep system is actually really quite nice, if very heavy. It's been nice for very cold weather. I'd love a quality, light, very cold rated quilt or bag but I can't afford it for a while unless something washes up at the thrift store again. In warm weather I use a hammock I also got there

A comforter from Walmart would not keep you warm in 20F. I would buy a 20F Coleman on Amazon. They're not as pricey or pretty but they're quality.

They brought back the Peak1 name. It's OK stuff for what it is. A bit overpriced for what it is.

I am a known collector of sleeping bags. I have more than 20 and 1 is a North Face Cat's Meow i bought in 1989, so I have a bit of experience on the subject.. I got the 0° Coleman Peak 1 from my work's incentive site. I would not have gotten it otherwise as I have Sea to Summit, Marmot, kelty, (pre-bass pro) Cabela Instint bags, etc... I took it out my Peak 1 on my November hunting trip. Temps were in the upper teens/ low to mid twenties at night. I had a sea to summit liner and a Mr Buddy Heater at the ready to use but never needed them. I was hot in this bag. I mean, half zipped up and still hot. I was shocked. I mean shocked. The only Coleman gear I have is a stove and a lantern as their gear ain't what it use to be.. and this bag out performed my expectations. Now. I was on a cot with a memory foam pad. I was dressed well. Do with this as u may as I have a slightly different bag. I am a cold sleeper tho. But my Peak 1 has more power fill down than my kelty and marmot and it looks very well made. This bag is coming on many more trips.

Mi first bag was Coleman mummy synthetic bag. 50$. Good till 32F, then you’re really cold. Second bag is Nemo disco 15F. ~300$ on sale. And I got Disco 30F for 200$. Coleman isnt compact but does the job. Nemo’s got some room at expense of worth but they’re compact AF

You can get a foam pad for a little ground insulation and a warm Coleman mummy bag for cheap. With enough warm winter clothes, eg a polyester filled winter jacket from goodwill, bib overall ski pants, a wool hat and warm gloves you can probably be warm enough and use those clothes to get around outside if/when your condition improves. If it's really cold add a balaclava for your face.

I’m a cold sleeper & bought a $40 Coleman mummy-style sleeping bag & it’s awesome! I think it’s rated for 40F but I haven’t used it at that temp.
