Reviewed by Kerri from Bozeman, MT on Sunday, July 30, 2017I 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.
Verified Buyer Reviewed by JL from Sandy, UT on Thursday, July 13, 2017Killer 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.
Verified Buyer Reviewed by Justin from Tennessee on Saturday, April 1, 2017Has 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.

Reviewed by Randaid from Vancouver WA on Monday, October 31, 2016The 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.

“What us it about this bag that prohibits it from being sold in Australia and New Zealand? Is it legal to take it into these countries for personal use?”
I am not sure what prohibits STP from Shipping to these two countries. Maybe cost? Its a sleeping bag, so I can not see why it would not be allowed in either country.
I now conclude that the prohibition relates to commercial considerations, not the content of the product itself. All the Marmot products sold by STP that I looked at have the same prohibition, be they tents, sleeping bags, pack and clothes. Marmot likely has entered a limited distribution agreement with a distributor in Australia and New Zealand. It should have no effect on an individual's right to bring Marmot products they own into these countries for their personal use.
I am unsure of what you are asking for. I received my bag brand new and it is a great bag.
“Is the 0 degree rating a comfort rating or the extreme rating? Is this european or US rating? Anyone know the actual temperature ratings on this?”
This is US rating. According to information listed under the product Overview: Comfort rating: 0°F
Justin, I don't have an authoritatively correct answer to your questions, but with almost 40 years of experience sleeping in down bags I'll say this. I'd presume temp rating is for "extreme", not comfort for two reasons. First, that's how virtually all manufactures seem to rate their bags nowadays - overly optimistic. Second, my coldest night in this thing so far has been around 10 degrees, in a double walled tent, sleeping in just expedition weight long undies. I was comfy until 3 - 4 am where I awoke just a bit too cool - could feel myself tensing up, plus my feet felt cold. After spreading a down sweater over my trunk area inside the bag I warmed up to 'perfect' in ten minutes.
Your best 'apple to apple' comparison to judge any bag, down or otherwise is measuring the loft on the top half of the bag. Once you've determined how many inches of loft your body likes for a given temperature, you can roughly factor in an additional one inch of loft for another 10 degrees of comparable sleeping comfort. My Radon bag measures 7 1/2" of loft total, with an easy 6" of it on the top half. This bag has continuous baffles which allows "shaking" down from the bottom to the top half of the bag. So far the most I've been able to get on top is that 6".
The one other dimension that's worthy of attention is the width of the bag. The greater the air space inside the bag, the more heat your body has to generate to keep it warm. It's easier to stay warm in a narrow cut bag than in a wide cut bag. Only you can decide what's too narrow or too wide.
This is why you cannot put faith in the temp rating of sleeping bags, especially sporting goods and department store bags. Now, at the other end of the spectrum there are two bag manufacturers, both made in the U.S by the way, that have a reputation for meeting their temp ratings at the comfort level, and not just the extreme level (not only will you not die during the night, you'll likely sleep warm and comfy): Feather Friends and Western Mountaineering. They're a bit spendy when you compare them to popular brands with the same rating, but their quality is peerless, and their ratings are pretty accurate.
