Rated 5 out of 5

Great Bag

Have used it a few time in low 20's and I was very comfortable and warm. It's a little snug with me being 6'1" 245 lbs, but I still got great sleep.

very nice, but heavy

For anything other than backpacking, this would be a great bag. It's just too heavy for that, though.

Stay warm

I have the Ignite o in an extra long size which I take to be an older model of the new product. I spend a lot of time outdoors and a reliable sleeping bag is a must. Even in the high deserts and mountains of the West down bags can be a proposition in the back country. No problems with the bag what so ever in three winters of heavy use. I chose the larger size for my 6 ft height in order to have room for a few clothes folded in with me and the bag is still the most comfortable mummy I have ever used. When it is colder than usual the bag goes in a canvas bedroll made by a fellow in Durango, Colorado and I have been very comfortable even when all the water in camp was frozen solid overnight and most of the temps were around 0 to 10 degrees or so. The locking zipper makes multiple season use very easy. A very good value for a very necessary piece of kit.

Get Schooled In The Geometry Of Comfort
Remember the trapezoid from 10th-grade geometry? Turns out, this funky ol' shape is ideal for helping sleeping bag baffles retain heat. The trapezoidal baffle construction improves on our best-selling Cosmic sleeping bag-and it's just one of the reasons the Kelty Cosmic Down 0 is still our favorite three-season superstar. We also love the natural-fit foot box for happier feet, and a PFC-free water-repellent coating for a healthier environment.
