Description

Brave the snowstorms that start wet and end cold when you sleep inside the Super Spiral Burrow #0 Bag.

Head deep into the BC backcountry and meet a big, wet Pacific storm system for epic pillow sessions in three feet of fresh. As the storm buries the tent outside, sleep inside the warm and dry MontBell Super Spiral Burrow #0 Synthetic Sleeping Bag. The Exceloft Insulation is as warm as down but dries much faster thanks to its silicon-coated fibers, so the sticky snow melting inside the tent and the nose-diving temperatures aren’t an issue.
  • Super Spiral Stretch System’s biased seams and elastic threads move with you throughout the night, keeping the bag close to your body to minimize open space and drafty air
  • Double draft tube, neck baffle, and tunnel hood seal you up in a warm cocoon when the weather lays down the hammer
  • Bags zip together to help conserve body heat in an emergency
  • Auto lock full-zipper won’t unzip as you toss and turn overnight
  • Left and right zipper bags available
  • Available for shipping only to US and Canadian addresses

LOVE LOVE LOVE

I have spent ~25 happy nights in this bag, it is super comfortable, warm, and the stretch system is fantastic. Not to mention the outside of the bag is fairly waterproof. A fair amount of rain built up on my bag and formed a bowl shape that had about 2 cups of water in it, i simply rolled the bag and the water drained off. Even when the bag does get moist on the outside the inside remains warm and dry. I love this bag so much i bought the 40 degree version for the spring/summer/fall. There are cheaper bags out there, but the sleep I get in this bag makes it totally worth it.

Most comfortable bag made.

I have the -20 exp long left zip version I gotta tell you I hate mummies HATE them I get claustrophobic, not anymore you can have a game of twister in one of these bags they are so stretchy. Bar none the most comfortable bag made. Warm to the temp advertised they don't lie like many other people I won't mention. The technique used to sow them keeps the down in place does not bunch up.

Does anyone know if you can use a compression sack to get this thing packed down any smaller than the stuffed size?

Best Answer Responded on

I have the 30 degree and I use a compression stuff sack that packs it way smaller than the non-compression one it came with. It works great.

Does anyone know if this bag has been EN tested? I'm looking at getting either this bag or TNF Snow Leopard but I'm not really sure how warm this one actually is

Best Answer Responded on

I can't speak to the EN testing, but from my personal experience the two brands that I will implicitly trust to deliver the "as advertised" temperature rating are mont-bell and Western Mountaineering.

I prefer down to synthetic insulation, both for its insulative properties and the weight savings, but you certainly save some money here over the comparable down bag.

I wouldn't get stuck on the EN rating; buy the bag you want and use it. If it performs, keep it. If not, send it back. I think that's the only way you are going to truly know, anyway.

My Single most favorite piece of gear

Okay, i've finally put this bag to... somewhat of a test. I've owned this bag for 3 years, but my most recent trip finally provided my with some cold-ish weather. I estimate around 15 degrees F. Wow... i was SO comfortable. I mean... WOW. I do sleep a little warm, but nonethelesss, i was at PERFECT temp, almost warm.
Washing of bag-use a front loader machine (I airdry, but that's not generally required)
Wear of item- despite the fact that most of my camping is way too warm for this bag, i've used it at least 25 times in last 3 years. Bag looks brand new.
MOST IMPORTANT QUALITIES- i LOVE THE STRETCH QUALITY! i sit "indian style" all the time in this bag. i can dress/undress with bag fully zipped.... wow. awesome. Also the cinch off footbox... amazing.

cons-bag is rather heavy/bulky. that happens though when you have this kind of extreme comfort. it's not overly bulky/heavy. just more than others on average.

personal info- i'm 6 foot, 185 lbs, sleep warm, bought reg size.

Can you tell us what type of sleeping pad you used? Thank you.

Responded on

i disagree. this is actually a pretty light weight for a 0 degree bag.

Perfect 1st Wasatch trip

  • Familiarity: I've used it several times

An amazingly warm bag. It holds up to true 0 degree weather. For car camping this bag cannot be beat! It is, however, a little heavy and bulky for backpacking, but still manageable. The stitching allows this bag to stay close to your body always, yet still stretches nicely while you toss and turn (like I AWLAYS do). I couldn't recommend any other bag for the price. Mine hasn't developed any odors yet and has resisted stains well, as long as tears. I fully plan on having this bag another 10 years for certain!

wonderful bag, sleep happy

Fabulous bag at this price. I've used it on several frosty nights while camping, and have been really comfortable. Our college son took us out backpacking in mountains he loves, recently, and this bag was excellent. We sleep in hammocks now, with underquilt sewn to the bottom; and this sleeping bag was more than I needed when temps were above freezing. With this bag, I skipped the tarp, saw the stars instead, and never worried about dew and warmth; great bag. Not very compact; not the lightest; but what a great price for warmth even if it gets wet. I had some wet nights in down, in my own college years; no more. The spiral design is great; the fabric is soft and light. Also, as a painter I appreciate the warm color even in the dark.

Nice Bag, comfortable, quality construction

weight should read 4lbs 8oz for regular per manufacturer.

warm bag but big, used in himalayas and high sierras in temperatures in the single digits and performed well.

if size matters go for down and buy one bag and be happy w/ it....

Overall, I'd recommend esp if you're looking for a synthetic bag or high value 0 degree

Is there any info out there on the durability...

Is there any info out there on the durability of montbell bags. Tested for X number of washes or X number of degrees in efficiency lost over time. Other companies this year claim new tech that lasts through many commpressions. Where does montbell stand?

Best Answer Responded on

I can't speak for loss from washing but I can say I own 4 bags for over 3 years. I do sleep in my 40 every night for over a year (it stopped my wife and I fighting everynight for covers, ha) I back pack in them and camp in them. I love my bags and I only buy these bags. I've yet to see any thermal loss at this point. fyi: I only compress when i'm backpacking, stored flat @ home all the time.

how wide at the shoulders is the montbell 0 degree spiral synthetic sleeping bag...i need a wide bag, mummy shape, especially at the shoulders.....thank you

Responded on

Write your answer here...This is the widest bag I have ever used. My shoulders are really wide, in fact every mummy bag I have ever had was tight, so tight I would have trouble zipping it up. Even Big Agnes Mummy bags. This is the first bag I can zip up reasonably easy and sleep comfortably in.

Best Answer Responded on

It is a pretty good width and the stretch system adds a bit of extra width also.

Responded on

Ditto all the above. If your a xl-xxl this is the only brand for us to breathe in

Great Gear, get the UL if you're paid

I bought this bag to replace my North Face Meow 20 degree synthetic. This is an amazing bag for the price. The construction and material is first class, and the spiral build is really cozy. Packed tight, dried quickly, and kept me toasty.I would have bought the UltraLight, but I'd rather carry an extra pound than pay 100$ more.
