From the end.

You don't gain much in percentage compressed, but you do gain some volume in your pack.

Could get smaller with a compression sack, but here it is right out of the box in the supplied stuff sack. (Note that there is a little perspective at work, making the sleeping back seem a little smaller than it actually is. Still... a small 0 bag!)

Amazing Bag

  • Familiarity: I've used it once or twice and have initial impressions

Just bought this bag and "field tested" it at a High Sierra lake last night. It's a zero degree bag that would probably actually keep me warm down to zero. I'm used to layering up clothes in my sleeping bags because I sleep cold. Last night I was taking things off. It didn't get down to zero, but it probably hit fifteen. I also like all the space in it. I'm a small person (5'2" and 115 pounds), but most bags feel cramped. This one didn't. Granted, there's a bit of a weight penalty, but this bag weighs less than my -5 Marmot Aiguille and that bag is a "short."
Bottom line: It probably won't appeal to the minimalist crowd out there, but I love bag. I've had other clothing products made by MontBell. They've all held up exceptionally well, so I'm expecting this bag will also.

Can anyone tell me definitively the difference between the "Super Spiral" bag and the "Spiral" bag? My guess has been that the "super" is extra stretchy, but I can't find the information anywhere... Thanks!

Responded on

The super is wider in the shoulders, and just a few ounces lighter than the non-super. Those are the only differences as far as I can tell, but that may be it considering there is only a $10 price difference.

Responded on

Thanks Laura. I was stumped because it seems kinda crazy for Montbell to keep a whole extra set of SKUs, product literature, etc. (and cause this sort of consumer confusion...) just for the sake of a $10 difference. Your answer confirms what I'd suspected: there's very little difference.

Still. For $10 I get to call it super. Vanity wins!

What is the difference between this bag...

Posted on

What is the difference between this bag by Montbell and the same bag but the non U.L. version? Am I saving about a pound of weight and an inch of pack space for almost $200 more or am I missing something?

Best Answer Responded on

No you're not missing anything. Basically the UL version is made with a higher fill power of down, 800 vs 650 fill. What this boils down to is that it will take less down to give you the same amount of warmth. Less down = less weight. Also the higher fill down compresses smaller than the 650 fill stuff. Bottom line is that if you're not counting ounces and can stuff it into your pack, then save yourself $200. However usually winter backpacking/camping means more gear, which means more weight, so the lighter the better. Also, if you're planning on car camping or only hiking a couple of miles then definately go with cheaper bag. Hope this helps with your decision.

Amazing 0 Degree Bag

I am a side sleeper and so the stretch system in this bag really appealed to me. I have never been more comfortable in a sleeping bag in my life. I was able to sleep comfortably in the fetal position, knees bent and all. The loft on this bag is also phenomenal, by far the warmest most comfortable bag I have owned. I am 5'9" and I have a bunch of room in the footbox so the regular would definitely fit someone up to 6'.

this is the one!

I expect quality from Mont-Bell, as I have for many years....I own the Alpine Light down sweater and always knew that they did down very well and that this bag would be good, very good. After several friends gave great reviews of the bag....I purchased it for my Guide/counselor/outdoor teacher son.
He is in the Wind Rivers this summer and sends back notes of how much he loves it and the great range of temps that it covers and how durable it is and how it gives him the much needed rest that you must have taking people out in the high country.
He is 6' ( we got a regular), 150 and sleeps cold....but, not with this bag.
I will expect it to last as long as my Sierra Designs down bag, that I bought in 1970..... But I will snag this bag from my son,to use, every time I can - which will not be much- I expect him to guard it.
If you afford it, get it....it is the 'one' !

I am very interested in this bag but am concerned whether its temperature rating will hold up in rain forests and coastal hikes of the NW and Western Canada. I sleep cold and have been using two synthetic REI bags layered, 15F and a 45F plus a silk liner ..and sometimes my montbell trou & sweater ...see what I mean..I need a bag! I also am concerned with weight and packing size as I often go out alone for 10-14 days. My pack is an Osprey Aura and if I go somewhere I have to cary a bear can, my space is very limited. I would appreciate advice from anyone with experience in coastal/rainforest areas with a down bag. Thx:-)

Responded on

Angie, this bag should hold up to it's 0F rating fine. However if you're layering that much and still cold, what's your ground insulation look like? If you don't have a warm sleeping pad (like a neoair xtherm or exped down mat) in cold weather, you'll lose a ton of warmth to the ground. I used to sleep really cold myself until I improved my sleeping pad and now I sleep "warm" by most standards.

Also the older REI bags had optimistic ratings at best...the newer ones are EN rated so should be more accurate.

Boom! Montbell Delivered

Superlight and really wide-expandable and comfy. I’ve owned several bags and had to move up to something a bit warmer for some higher elevation trips. This by far is the warmest and most comfortable out of all the ones I’ve owned. Everytime I get it in, I don’t want to get out. No other bag compares! Highly recommended!!

Responded on

John, I have a question for you. I have had a Western Mountaineering bag for over 10 years, the MegaLite. I really love it, very packable and light, with excellent construction. I have went on countless trips with it, even lived out of it exclusively for 7 months in Afghanistan. Now I am looking at getting a new bag, the Western Mountaineering Versalite. But you say that this is the best bag around, and after lots of research on my own I have to agree it looks like it might be "the one". I guess what I am trying to ask is do you think that this bag is superior to the Versalite? Appreciate any input you have!

Responded on

Hi Kyle, they are both great bags. I have used a WM bag before and they are great! However I would lean towards the Montbell. I use this bag for Alpine climbing trips where its cold. At first I wasn't sold on the Stretch feature but after a couple of trips in the bag I wouldn't own any other type. I like to sleep on my side with my legs in a open scissor position, with the stretch it is comfortable to do and doesn't feel constricting. Personally I would only pick the Versalite if you are concerned about weight and saving a couple of bucks. It's all about preference, but you can't go wrong either way. I hope this helps.

Responded on

John- Thank you very much for the insight. I sleep the same way so I am glad to hear that you found it more comfortable. My WM bag fills the niche for a 3-season bag, and I think this one will be my high elevation/winter bag. I have cut weight in so many places in my pack that my bag can weigh an extra 13 ounces. Once again, great advice- thanks!

but what does it weigh? And is 0deg inF or C? Big Difference!

Best Answer Responded on

0° is in F. This is the most anti-metric country in the world, after all. USA! USA!

It weighs 2 lbs. 15 oz. Oddly enough, that's 2 oz more than last year, but it's all extra fill. I have no idea why they needed to add 2 oz of down while keeping the same temp rating.

Responded on

You will not find a better bag. I had the older model in a regular and just got the new one in a Long to have more space for drying clothes while I sleep. With the older one I have used it all over from -20 to 30 degrees F. I have done tons of research and tested many bags and this one just kills it.
