    I love this bag. For me, there is no way this will ever be a 0 degree bag (even with my nice liner). Nor will ANY bag be a 0 degree bag. I freeze. PERIOD. But enough about my shortcomings as a human. First off, I'm a short 5'3" female but I need the extra room through my shoulders and knees because I practice Judo in my sleep. I have enough room to toss and turn without waking myself up. I don't know how "long" the bag is...it's whatever is in this add but I have plenty of room at my feet to stuff a coat for extra warmth. I usually end up kicking my arms out and rolling over on my stomach and using the hood as my pillow scrunched up under my head. I'm sure that will change as I use this bag in the colder weather. This bag is cozy and warm and comfortable at the temps I've used it at with low 50's so far. One night I just laid in it with my liner. I didn't even zip it up. As it gets colder and I layer more, I am positive that I will be able to use the bag at lower temps. This bag is worth it. I am happy. I will update as I use it in colder temps.

    Killer Bag? Yep. Used it right after I got it and it will definitely keep you warm. Love the great loft which takes some time to achieve after being in a compression bag. Foot box is great and the baffle kept out the cold air at 12000 ft. I would like to see a little more down in the draft collar but it did the job. I especially love the oversized mesh storage bag. This will help keep the down from always being compressed . Great bag and I got a great deal From STP.

    Has about 7-8in loft. Looks well built. I haven't field tested it yet, but lying inside of it in my living room, I was sweating within a minute. It compresses down nicely.

    I bought the regular size. I am 5'8'' and weigh 170. Plenty of room inside this to roll around in. My wife is 5'8 130 and it completely enveloped her.

    The only thing that's hard to take is the bright orange color. I guess it could be a good thing for aerial search & rescue - high visibility.
    What's great about this bag is the continuous baffles. The down can be shifted from bottom to top or vice versa to accommodate a wider range of temps. The cut is just about right for me. I like room to turn easily and to sleep with a leg cocked sideways, yet not so roomy that efficiency is significantly compromised. This bag is virtually the same cut as a Feathered Friends Osprey if that helps. The shell is Pertex Quantum - great choice for strength and breathability. The DWR works great, as on any new fabric. Time will reveal how water resistant the weave is on its own.

    Stuffing it in a stuff sack is a pain as the fabric is so wind proof the air struggles to flow out of the baffles - don't be in a hurry. Two things that I would change if I could custom order this thing other than the color: one is to put more down in the draft collar - what's there is a bit skimpy. The other is a wider length of reinforcement fabric along the zipper to minimize catching. The fabric seems to catch fairly easy, but this is nothing I'm not used to from my other bags so I'm already in the habit of using both hands when zipping.

    800 fill down, an honest 7+ inches of loft, and a Pertex shell for $300. I can live with orange.
