    Marmot 15°F Krypton Down Sleeping Bag - 800 Fill Power, Mummy, Regular
    I bought it to use on winter mountain camp.
    It became a favorite, because it so lightweight Down defender model.
    I want to use it early.

    Nice bag. Light, 2.2 lbs with stuff sack (regular). Nice loft to it. Feels warm but have not used it yet.

    Only used it for two nights so far. Slept very well Outside temps in the 50s had side sipper half open.
    Very happy with this sleeping bag Highly recommend it.
    I got a compression bag to use with it. Will not use the original bag that it comes with for anything.

    I have used the bag several times in Shenandoah and will be using the bag soon in Peru. I'm a fan. I thought it would be too long (I'm 5'4") but when I'm tucked all the way inside it's actually the perfect amount of space. The left side zipper takes some getting used to. It is definitely a warm bag. Im a naturally cold person no matter the weather outside and haven't had problems staying warm yet! Stuff sack is small but it fits snugly into it.

    I was amazed at how light this bag is and how well it packed down for the type of bag it is.
    I bought this bag specifically for a Mt goat hunt where reducing the amount of weight that I am carrying is crucial. This bag is exactly what I was looking for....

    This was my wife's first 800 fill sleeping bag. We have taken it out once already on a cross country skiing trip. It kept her warm and comfortable, outshining all other sleeping bags in the yurt. Moving up to this 800 fill is a great option if you are willing to invest.

    This is my first 800-fill bag, and it was worth the money. I used it on the AT in VA, and the temps dropped to 25 at night. I was in a Marmot Tungsten 1-person tent on an Exped pad. The bag kept me totally warm. I wore only my socks, light pants, & an LLBean fitness top. I actually got hot at times & had to unzip the bag. My only complaint (4 stars vs 5) is the zipper can be a bit tricky. The pack packs nice & small into a Sea Line bag. In fact, it's half the size & weight of my Marmot Kestrel 15 synthetic bag.

    Man, this thing is so warm! That pillowy 800 fill loft is just nuts! And at just over 2lbs! Literally, my only gripe is that it is so lofty it takes a bit of wraslin' to get it into the tiny stuff sack. Get this bag if you want to stay warm backpacking in cold temps.

    I think I've had this bag about 6 months. I've probably used it over a dozen times. It is a very warm bag I think I've only used in the freezing range a couple of times but am often overheated so it should do well in fall and spring and even winter with the right layering. The only drawback I've seen so far is that it seems to be losing a few feathers of down after every use, which I'm sure is to be expected, but is a little concerning nonetheless. I've used the bag all over, from Ouray to Zion. Best bag I've owned thus far.

    Used this bag for the first time this previous weekend, kept me super warm! Tons of room to move around in. Packs down nice and small, fit it in my 10L compression stuff sack. I looked at many sleeping bags for a long time before finally buying this one. Extremely pleased with the purchase!
