We don't use the word 'ingenious' very often.
As far as sleeping bags go, 3.25 pounds is really light. When you're talking about a bag that will keep you warm in the dead of winter, however, 3.25 pounds is ridiculous. On top of the warmth, the Storm King 0-degree Sleeping Bag has a roomy rectangular design and can even be zipped together with another rectangular bag. The main reason for this ultra-light weight is the fact that Big Agnes eliminated the unnecessary insulation from the bottom of the bag. When you're sleeping on top of insulation, it doesn't keep you warm because it has no loft and therefore no air istrapped inside to keep you warm. Instead, Big Agnes put a Sleeping Pad Pocket in its place, so you have the trapped air in the sleeping pad keeping you warm and at the same time you can't roll off the sleeping pad.

Five years with the Storm King
- Familiarity: I've put it through the wringer
I bought the storm king from the Bap store in steamboat in 2009, and the bag has stood the test of time. This is the longest lasting piece of equipment in my backpacking arsenal with the exception of my buck knife, this bag refuses to quit. Here are my notes on the Storm King.
-First and foremost, I am a huge fan of Big Agnes signature integration of sleeping bag and sleeping pad. It cuts down on bag weight, makes it impossible to roll off the pad, and it just plain feels right. I have heard complaints from side sleepers that the bag/pad integration is not comfortable, but I am a side sleeper myself and I love it.
-The model I purchased is a bit different than the 2013 model, the biggest difference being the addition of downtek, Big Agnes's signature water repellent down. I have not had experience with downtek so I cannot comment.
-At Temps sub 10 degrees you can start to feel a bit of heat seepage at the seams where the bag and the pad meet. If you are planning a trip to the yukon, you might want to consider a different set up.
-Big Agnes has unbeatable customer service, I have had several problems over the years and they have always told me the same thing, "send it in, we will fix it".
-Lately I have noticed some down loss out of the seams , and it doesn't hold heat quite as well as it used too, but after five years of constant use I am not really surprised. This bag has been worth much more to me than what I spent on it.
-If you are looking for a sleeping pad to use with this bag I recommend the Q-core SL, its light, comfortable, and one of the best insulating pads on the market.
-Lastly, This bag is named after a wildfire that occurred on Storm King mountain, one of the most deadly in the forest services history. You can read about it in John Maclean's gripping account "Fire on the mountain."
10/10 I can't recommend this bag enough.
Will a BA triple core pad of appropriate...
Will a BA triple core pad of appropriate size fit in the sleeve?
Yep, Big Agnes designed this bag for use with a sleeping pad to keep you better insulated.
- Familiarity: I've used it several times
This is an exceptional bag. It is very lightweight for the size and being down allows it to compact very small (you can stuff it in a 10L Outdoor Research compression sack). My previous bag would take up almost all of the large sleeping bag compartment in my pack, while the Storm King leaves plenty of room for sleeping pad and other things.
I have yet to truly test the 0 degree rating, but have had it out for some chilly nights. With the Insulated Q-core pad I have yet to sleep through a night with the bag zipped up, it has been plenty toasty.
If you are remotely close to the 5'10" break point for regular and long, get the long. You will enjoy the extra room.
I do enjoy the extra wiggle room this bag provides by skipping the insulation in the back. You just have to take care of your pad and you will be fine.
Nice and toasty
For the $ your not going to find a better Zero bag out there. Downtek, which is really amazing stuff. Stays dry 10 times longer than regular down and drys out 33% faster. If the synthetics didn't cost so much less downtek and dridown would make it obsolete. Super warm bag, vertical baffling helps keep your little piggy's warm with all the extra core heat sent their way. The weight isn't bad but you do have to have a 4 seasons pad to make this a true zero bag. There is no insulation on the bottom, the pad is your insulation.
