Marmot Snowy Range

This was my first down bag and I like it a lot. I'm 6'5" and the long version fits me great and the hood system is nice. I used it last night and it got down to about 15 F and I wasn't getting terribly cold but my pad kept slipping away from under me and the cold snow on my back quickly woke me from my sleep, but the rest of the bag kept me pretty warm for being in a snow cave. I'm generally a warm sleeper and with a good bivy I'd say this bag is good to about 0 F but not much colder. Very lofty and comfortable. No problems with it other than that.
