For the reasonable price it's a very nice bag, light, packs small, and fairly warm. I have doubts about the 20F rating but I took it quite high in Colorado in late May, and I was very warm even with the hail/snow outside. A inner liner definitely helps.

If you are on a budget (and who is not on a budget nowadays?) this is a decent bag. It's fairly warm, although 20 degrees may be slightly optimistic. It does have an internal chest baffle. It comes with a compression sack, and packs down to about 8 X 12 inches. If you are 6 feet or taller, I would definitely get the long.

This bag is a great product. Its super lightweight, highly compressible, and lives up to the degree rating. i took it backpacking a few weekends ago on a cold, windy night here in colorado and i stayed warm the whole time. its sweet to have a bag that takes up hardly any space in my pack.

This is my first down bag after years of packing a huge zero degree synthetic bag. I'm saving several pounds and lots of room in my pack but I was worried about getting cold. A cold snap in the Canyonlands had me unexpectedly testing this at 18 degree temps. I was wearing my long undies, fleece, and beanie and using a downmat, but I stayed warm enough all night and slept fine.

I just bought this bag and have only used it in moderate weather thus far, so I can't testify to the degree rating. As for the design and quality of the bag, it packs down small, is lightweight as promised and works great. I can't wait to take it backpacking this summer!

Got this off steepandcheap not long ago. Stayed warm and slept well in 20-30 degree weather wearing long underwear and a fleece top. Probably didn't need the fleece. Good down bag at a great price.

The bag was light wieght which was fantastic for packing in but If I can I will return it for a warmer bag. I seriously doubt this bag is really 20* I had to use a flannel liner to stay warm. Although for the $ it might be worth it for someone that only camps/backpacks a few times a year.
