This is NOT a 20 degree bag,
Verified Purchase(What's this?)
This review is from: Kelty Cosmic 20 Degree Down Sleeping Bag (Sports)
Just took this overnight in Mt. Baldy in California and was very uncomfortable in 34 degree weather. Luckily, I had a down parka to wrap around myself to avoid a whole night of shivering. I could feel plenty of cold spots through the bag and in the morning I found out why. Holding this bag up to the sunlight, you could see how poorly the baffles were filled with down - - it was like there were stripes of down interspaced with stripes of virtually nothing in between the next stripe of down. The "cold" spots were equal to the "warm" spots.
I'll keep this bag for a summer bag, but don't buy this if you expect to stay warm anywhere near the 30 degree mark.
PROS: Light in weight, and packs down small. Comes with a nice stuff bag. Price is good for down.
CONS: You'll freeze your buns off in cold weather, ie, poorly rated for a 20 degree bag
I would NOT recommend this bag to a friend.

Were you using a pad underneath? I've found it very comfortable down to 30 degrees (haven't had a chance to use it below that), but I prefer to sleep a little cool anyhow.

Yes, remember that the ratings are given when using a sleeping pad and wearing long underwear.

I was using an exped down mat shown here:
Exped DownMat 9 Pump Sleeping Pad
I sleep a little cold, and my hands and feet get very cold when the temp dips. Cheers...

In cold weather I would suggest a closed cell pad as it adds insulation where as air mattresses hold a very low R rating almost nonexistent R value. I would suggest a thermarest as they are very light Therm-a-Rest RidgeRest SOLite Sleeping Pad
I live in the south but it gets cold in TN and its a different cold than up north, lived in RI for 15 years and I remember walking around in jeans and a t-shirt in the snow. So when it dips down to 30 I use a Sleeping bag liner as well.
And I am not putting down 550 down no pun intended but it defiantly is different than 800 down in the way that it settles especially after being put in a stuff bag needs a little extra lofting. But also I am much more happy with this 20 degree bag than my last synthetic 20 degree bag. I love this bags versatility I use mine year round, not to hot in the summer and just barely warm enough in the winter. Although I have only gotten down to about 26 I was in a very nice 4 season tent with a closed cell pad, thermals and a sleeping bag liner. So really to each his own, but for the price you really cant beat it, way better than synthetic for the same price.

There are insulated air mattresses which have higher R values than closed cell pads. The R value of Thompson's air mattress is 8, much higher than any and all Therm-a-Rests.
I would agree with your statement for uninsulated air mattresses though.

I was able to sleep ok in 28 degree weather with three thermal layers of pants and shirts. I would say it would be an uncomfortable sleep below 32 degrees unless you wear a lot of warm layers or a sleeping bag liner.

I had the same issue with this bag and the female version. We both had air mattress pads that were insulated. Temp got down to 32 F and it was a miserable night. Completely agree this is a summer bag.
