4.0 out of 5 stars
Great bag, but is it -20?

I bought this bag on a special. The cost was worth it. The bag is big and a bit heavy but that's to be expected for the price. Comes with a sack, but not a compression one. Definitely a car camping bag. I'm 5'6" 175lbs and it fits me just fine. Enough room to move my arms around too when fully zipped up - 32" (64") at the shoulders. Quality seems good.

Here's why I gave it 4 stars. The bag is rated by ALPS as a -20 f bag. There's no international EN rating which would make the temp rating more universal/ accurate. So, I bought it knowing to not put too much thought into that -20 number. I went camping for a weekend where the temps went down to 30 to 35f at night. My tent has no mesh other than the vents and a window that zips closed. With vents open, and on a cot with a 3.5" insulated pad I was nice and comfy and warm. I wore a cotton long sleeve shirt, socks, a ski cap, and just my underwear (not long johns). Sure, I slept wonderfully, but I wasnt hot. I should have been in a -20 bag at 30+f . I wont have a chance this year to get to test it at a much lower temp, but I dont think it will be able to handle -20. Maybe 0-20f would be doable depending on your tolerance for cold. I'm good with that as I dont do super cold camping.
