ALPS Mountaineering 20°F Echo Lake Sleeping Bag - Synthetic, Mummy

I took this out on a night that dropped into the mid 40s, so I thought it would be no problem, but I had to bundle up quite a bit to stay warm. I had a thermal shirt, hoodie, sweats and ski socks on and yet my feet and thighs were still chilly (the only areas without 2 layers of clothing). My fool husband wore boxers and a tee shirt and turned into a husband-sickle. As my headline says, I do think you'd stay alive at 20 degrees, but you would be very cold and unhappy. Take the rating with a grain of salt and buy a thermal mat (which we did not have)and bundle up more than you would expect to and you'll be fine. Other than that, it's a nice quality bag, the zippers seem sturdy and the padding is enough that a mat isn't necessary (though I would recommend one for warmth reasons...).

Excellent price on a good sleeping bag.

Have not used this out in the elements yet. Comfortable

I wanted to take my 5 and 2 year old son camping and needed gear. I bought this sleeping bag and it was exactly what I was looking for. Its warm, comfy and stores nice. I just wanted something simple and nice and this is it. Temps. got down to 45 degrees and I was nice and warm with just sweat pants on. Only used twice but worked great both times.

It is warm and light but I am 5'9 and it fits just right. I wouldn't want to be 6 feet tall and use it. Good for backpacking as it is quite light.
