A lot of warmth. A lot of light.
There are no other bags I've found that will give you the weight, quality and warmth that Marmot has packed into this ultralight setup. I used it as a multi-purpose summer bag and a small, packable hut tripping bag for winter ski pursuits.
It's been a helpful addition to cut my pack down to 40l from 60l range.
The warmth collar is a great addition and the construction throughout is top-notch. The zipper occasionally gets snagged, but I've never owned a bag that hasn't. I have had a couple of breathability issues, so the full length zipper has been handy in letting off steam.
Best bag I have ever used
- Familiarity: I've put it through the wringer
The 30 degree Plasma bag is fantastic. It?s my summer back for Alaska(50 degree nights, down to low 40?s). Some other people are complaining about it having a full zipper, a draft collor and a ?pillow?. I don?t see were the complaint is, the bag still weights less then most ultra-light bags. Sure Marmot could have saved weight with a half length zipper, but the bag?s weight is still on par with its competitors. Bottom line: yes it is a full-featured bag, but it?s the lightest full-featured bag and is lighter then most ultra-light bags. Other then that the build quality is superb. While I have only had the bag for one summer, the durability is excellent so far.
The only downside is that it makes me want to upgrade my 15 degree bag to the plasma as well.
Hydrogen vs plasma? Which one is the...
Hydrogen vs plasma? Which one is the better sleeping bag? The plasma is pretty steep in price, but what features give it the advantage, if it has one, over the hydrogen?
Higher quality down 900 vs 850 and 3 oz lighter. They say that vertical baffles insulate better than horizontal and I can see how that makes sense, but in my opinion it's not enough to justify amount of increase in price. I have the zero degree lithium and it rocks, I would expect the hydrogen to perform the same for its temperature rating.
I seem to sense that some people think that a sleeping bag with higher quality fill will keep you warmer just because the fill is better, and is, therefore, better. But the only difference in, say, a 600 and 900 fill bag (assuming same model) with the same temp rating will be the weight and bulk of the bag. If you're car camping, cheaper is "better" here, but if you're backpacking, lighter and more compressible is "better." As Alexander said, there is a small weight difference, and vertical baffles, but, in theory, if the bags are rated to the same temperature, they should both perform the same while sleeping.
Does anyone know the fill weight?
Does anyone know the fill weight?
Also, I am 5'11'', should I get the regular or long version?
900 fill, it's in the description.
I think he meant how much the fill weighs...
11.82 oz / 335 g
as per Marmot's website.
Temps? I think the 30 would work better...
Temps? I think the 30 would work better for most of my trips than the 15, as I will have some nights up to 70 and as low as 20. I figure I'll just unzip and use more like a blanket on hotter nights? And layer clothing on colder ones. This will be my first high end bag, weight and stuff size are important to me. My question is will the 15 burn me out on a hot night any more than the 30? Enough to make a difference in my choice? Maybe I just need two bags since I'm looking at such big temp differences?
I would go two bags, but I would slurge for the 15 to keep you warm on those cold nights and then pick up a cheap 30-40 degree down bag for those warmer nights on one of the many sales going on right now with the summer coming to an end soon. This is what I did last year and I'm very happy.
I think I will just look at two bags. I like the stuff size and weight of the Plasma so I might go with their 40 for summer. Also checking out some Western Mountaineering for a winter bag, thinking of going lower than 15, I guess it couldn't hurt to go 0 degrees if I'm only using it for colder trips? Thanks for the advice
I've read a couple reviews from people complaining that this is not a true "ultralight" bag because it has a full zip and built in pillow etc... All true, but the "extra" features make the bag more usable, even if it is and ounce or two heavier. I'm a tall guy (6'3") and the fit is good in the long. The pillow was frankly nice to have and the draw strings for the draft collar and the hole were easy to operate from inside the bag in the dark. 30 degrees is a bit generous, but 40 with wind was no problem. Storage sack and stuff sack are also top notch in quality. No feathers leaking after 10 days of use.
Great 3 Season Bag
I have had this bag on a 1 night trip which went down to 50F. Used it as a blanket worked beautifully. Expect to take it to 20F trips with additional sleeping layers no problem.
I heard that the only way to get 900 fill...
I heard that the only way to get 900 fill down is by live plucking geese, does Marmot comment on their down supply chain? I'm not sure the extra fill power is worth that kind of torture, I don't really care about geese but I don't need to go out of my way to $uck with them.
900-fill down is available from humane sources. Marmot says they source down from geese that have been raised for food, and that they harvest the down only after the geese have been savagely murdered. Doesn't that make you feel better?
I heard that 900 fill DUCK down can only be obtained via live plucking. 900 fill GOOSE down, on the other hand, can be done after the animal is dead.
Other summer weight bags are better!
Although the Plasma 30 is very comfortable and fashioned from some of the best ingredients available, we believe that other bags perform better in the ultralight summer category. For one, the Plasma has a full neck baffle with two snaps and a drawcord. While this feature is well designed we dont believe it belongs on an ultralight summer bag. Similarly, the hood is very comfortable, but almost too comfortable. Marmot stuffed extra down into the back of the hood to make a mini pillow. These features dont add too much extra weight, but they illustrate that the bag is designed more for comfort than for performance.
Baffle design: continuous horizontal baffles found in the Feathered Friends Merlin and Western Mountaineering Summerlite provide more versatility than the Plasma's vertical baffles. The Flow Gates (7-8 in each baffle) are made of no see um mesh neeting and cover most of the baffle. You can pass some down though them, but it's quite difficult. Continuous baffles are better because you can shift the down to the top of the bag if it's very cold and to the bottom if it's warmer.
Another potential drawback is the shell material, Pertex Quantum. Though superlight and surprisingly durable for its weight the material offers virtually no water resistance. Other materials, such as the Pertex Endurance UL offered on the Feathered Friends Merlin, are nearly as light and more water resistant. You cant go wrong with the Plasma 30, other bags perform better and are cheaper.

Marmot Plasma Sleeping Bag

The Ferrari of sleeping bags
This bag is a work of art. The 10D fabric is silky soft on your skin, the hood cinches down to create a nice seal, and the draft collar is stuffed full of luxurious down and adjusts smoothly. The interior fabric is a bright, translucent green and the exterior a svelte, glossy black. The Plasma is neither constrictively narrow, nor is it roomy, striking a nice balance between warmth and spaciousness. The footbox is well constructed, and the full length zipper operates smoothly, providing venting or clean mating with a Helium or Pinnacle. The Plasma comes with an ultralight stuffsack as well as a nice mesh storage bag, with "900 FILL" emblazoned on the bottom in huge, heart-racing numbers. Marmot has cleverly used synthetic insulation in the draft tube to keep it evenly stuffed, and it works quite nicely.
With the stuff sack, the Plasma weighs in at 1lb 8oz on my scale. The EN rating of 32ºF seems accurate, I was cool but comfortable sleeping outside on a 30º night in Joshua Tree NP with a hat, socks, and midweight baselayer.
But is it worth $420?
Depends on who you are I guess. If you absolutely must own the best of everything at all times, this is your bag. Its primo. If you want to get the most for your dollar, however, you can do much better. The Hydrogen, for example, is EN rated 3º warmer, costs $80 less, and only weighs an ounce or two more*. The Hydrogen's warmth rating is achieved without a draft collar and with roomier dimensions, making it far more comfortable. The thicker fabric on the Hydrogen holds in the down better (the Plasma sheds feathers from the seams occasionally) and its horizontal baffles mitigate down shift - a big problem i notice with the Plasma's longer vertical ones.
Overall, the Plasma is a very unique and worthy piece of gear, and I'm glad I bought it, but I wouldn't necessarily recommend it, nor would I tell you it's worth the money.
