Stoic Somnus 15 Sleeping Bag: 15 Degree Down -

Like an oasis of warmth amid the cold of the wild, the Stoic Somnus 15-Degree Down Sleeping Bag brings supreme comfort to your shoulder-season camping missions. Lightweight Pertex shell material fends off the bumps and bruises of a life lived in the woods, and 850-fill down insulation protects you from the surprise of an early-fall overnight frost. Stoic dialed in the fit-and-finish details of the Somnus with a center main zipper, vertical torso baffles, and a foot water bottle pocket because it's the little stuff that can make or break a solid night of rest in the backcountry.


  • Pertex shell material creates a durable outer shell without a nasty weight penalty


  • Winter-weight, 850-fill down insulation provides supreme warmth without weighing down your bag
  • Down insulation is highly compressible to make packing a cinch
  • Vertical torso baffles ensure that the down insulation stays put even if you sleep on your side


  • Center-oriented main zipper makes it simple to get in and out of your bag without having to search around in the dark
  • Zippered pocket at the footbox holds a hot water bottle to keep your toes toasty on frigid nights


  • Draft tubes prevent chilly air from entering around the neck so your heat stays inside your bag

Stoic Somnus 15 Sleeping Bag: 15 Degree Down Reviews:

Positive Reviews:

Great Bag

Allow me to preface this by saying that this sleeping bag is my first high loft sleeping bag, and I did not own a down bag before this one.
This sleeping bag is amazing.
Many people have had problems with the center zip falling into their faces, but Stoic has fixed this problem. There is now a flap that the zipper can be tucked into in order to avoid it becoming loose and dangling in your face. The shell material works very well - I held the bag under the faucet and saw the water roll off. I haven't seen much condensation on it, so I can't really comment on that right now. The compression sack isn't great, so I might suggest getting a new one. I wouldn't spend the list price on it, but I got it for $210. I've slept down to 23 degrees F in this bag comfortably, so I can't accurately comment on the accuracy of the temperature rating. Also - just a minor complaint - there isn't a neck baffle, which isn't a huge deal, I suppose. However, there is an ample zipper baffle.
At 5' 10" and 130 pounds, this bag (in regular size) is spacious and luxurious. The center zip is awesome! It never snags! I've never been cold in this thing!! I'm sure this bag isn't as nice as a western mountaineering bag, but for me in Colorado doing 3 season backpacking, this is a great bag. I plan on buying the 30 degree version in the near future.

Solid Choice

I have had this bag for a while and I really like it.
The center zip does take some getting used to. Fully zipped the cold metal zipper has been known to fall on peoples' faces, but to me that is not the end of the world. This is a known problem though, so I'm not sure why Stoic hasn't addressed it.
The size of the bag works for me. I'm short, so the length is more than adequate. I move around in my sleep and have never had a problem with the width either.
I like how small this bag packs down. The included stuff sack is really solid.
Warmth wise this bag is good, but I can't say I would sleep in 6 degree weather like the previous reviewer. I sleep cold though, so maybe it's just me. If you're a cold sleeper as well, this bag should suit you down to around freezing. Anything below that and you should pick up a good bag liner as well.
Overall, this bag is light weight and a good value if you wait for a sale. Recommended.

Lightweight and warm

850 fill that packs down to about 9 inches square and weighs a few pounds. Easy to carry and warm. What else can you ask ask for? Top zip is convenient so you can let out some heat from the top and not get chilled on one side of your body. I have used this bag on 20+ mile mountaineering trips in Colorado, sleeping at 11,000 feet with temps in the 30s. I was not in the least bit cold. Not tested at its rated temperature though. I would recommend this but not at full retail price. It seems to go on sale a couple times per year.

This is my second Stoic sleeping bag...

I love it. I now have the older 30 degree, and now this one. I love the weight of the bag, and the top zipper. The material seems pretty thin, but I have not had any trouble with my 30, so I'm guessing this will work just as well. I only sleep out under the stars with these bags, and with the weight savings on these super light down bags, I've somewhat turned into a very light backpacker. Love it! (I did get the bag on sale, thgouh)

I love this bag. I love that the zipper doesn't go the length of the bag. I roll around a lot. So, I never end up on the zipper. It's pretty epic! 850 fill = WARMTH! I slept out in 6 degrees with this and the Stoic medium sleeping pad and I was TOASTY warm. Even in my crappy man made shelter that had a constant breeze. I'm really hyped on this bag.

Neutral Reviews:

Too narrow for a mover

I like the bag enough to keep it. It's warm and the tall is REALLY tall giving my 6'3" plenty of space to move "vertically." But it's pretty narrow meaning a back sleeper or a side sleeper option is really all you got. I tend to sleep with a bit of a jack-knife orientation - one knee out wide and I couldn't move much before reaching the max width of the somnus.
I also can't support the top zipper. In theory, it's a great idea to avoid sleeping on the zipper for a side sleeper. But I found it failed for a couple of reasons:
1. The bag doesn't always move with you. I could easily turn to one side leaving the hood flat on the ground and the zipper on top. I actually had to work the bag onto its side with me in it. This led to #2
2. The bag unzips easily. Unless I was diligent about getting the zipper all the way closed and then holding it as I shuffled, it popped open and let the chill in. I was constantly trying to rezip it.

A little weak

Very nice bag. I got it on sale so I didnt have to pay the 350. I do have a gripe though. I noticed striations occurring on one side of my bag in the torso and the down is leaking out. I just sewed it up, but it only took about 3 uses and it was happening. Still a nice bag though, all in all.
