Warmth when you need it most.

Even though you’re not sure what to expect from Mother Nature this weekend, you can expect a good night's sleep from The North Face Blue Kazoo 15-Degree Down Sleeping Bag. The lofty 650-fill down is supplemented by strategically placed synthetic insulation that keeps cold spots under you at bay.

  • The 650-fill down insulation retains your body’s warmth and provides a higher warmth-to-weight ratio than synthetic-fill insulation
  • Vaulted footbed won’t constrict your feet and helps promote circulation to your lower extremities
  • Ergonomically shaped hood provides extra comfort, improves the bag’s warmth-retention, and reduces its overall weight
  • Synthetic anti-compression pads are strategically located in areas where your body typically comes in contact with the ground to create more durable insulating layer and reduce heat loss through convection
  • Trapezoidal-shaped baffle system ensures a consistent fill volume to reduce cold spots
  • The grey goose down in this bag is purchased from small, family-owned farms that do not live-pluck or force-feed the geese

Decent for the price.

  • Familiarity: I've used it several times

I've owned one other down sleeping bag, and this one kept me as warm and comfortable as my other in about 10-15 degree temperatures. However, this one seems to always attract more static electricity. Other than that it's about the best 15 degree down you'll get for the price.

Wasn't thrilled with it

  • Familiarity: I returned this product before using it

In comparison this bag has more loft than my stoic 850 fill 30 degree, but with a liner I believe my stoic can do everything this bag could do in a lighter smaller package. I decided to return this one and look into a western mountaineering bag to fill my niche in a light winter down bag. USA!

I understand that a right zip and a left...

I understand that a right zip and a left zip can be combined to make a two person bag. This would be ideal for me and my girlfriend. My question is whether this would work with a long bag combined with a regular bag or would the difference in length be an issue. Thanks for your time.

Responded on

I tried to zip my boyfriend's and my bag together (both Marmot Trestles) and the problem that we experienced was that the zipper lengths are different on the male/female versions of the bag. I'd imagine you might have the same problem trying to zip together a regular bag and a long bag, so I'd recommend checking first to see if there is a discrepancy in zipper lengths.

Just OK

  • Familiarity: I've put it through the wringer

Wish I would have done more researching on this bag but I got it on discount from a local retailer. It's a light compact bag. IT IS NOT A 15 DEG bag. MORE LIKE 35+.
I'm a cold sleeper anyway and I was hoping to be able to use this bad for September archery hunts in the high country. I've used this bag for over a year now on a dozen or so multi-day bivy trips with a bivy bag and top-dollar pad. I get cold in this bag with long underwear in temps around 40. I have had to sleep in several layer of clothing to stay warm in temps around 30-35. I've had to used a fleece liner in temps below 30. Wish I would have bought a -10 bag!

My first down bag, love it!

Love this bag, lightweight, soft cozy material, I'm 5'11 and had bought women's bags in the past but they'd always been too short. This has a little extra room for me and seems warmer than my synthetic bag that was rated at 15 degrees. Definitely worth it!

I will be treking in Nepal this coming...

I will be treking in Nepal this coming Oct/Nov 13 for 21 days - I'm told to get a bag which will be warm & comfy for up -20 Celsious - we will camping up to altitude of 4000m under tents. PS: I'm a female. Would this type of bag be ok?

Please, do yourself a favor and consider getting a bag that's going to hold up the the extreme conditions that you will be facing. The 15 degrees F you see this pack rated to is the most extreme conditions you should put this through, not the comfort rating. I have been in -5 degree F temps with the wrong bag and I honestly felt if I let myself fall asleep that I might not wake up in the morning. Remember that you will be spending upwards of 8 hours of your day in your sleeping bag, that's a total of 7 days on your trip that you could be miserable if you get a bag that's not going to meet the standard of your trip.

The bag I have listed below is more along the lines that you should be looking into, something that will keep you warm if temps do decide to drop, something that will be light and packable for when you are trekking, and something that should regulate your heat more efficiently :

Hi Brigitte,

Seriously listen to Wayne's advice. You're not only facing sleepless nights and comfort issues, you're potentially talking life or death. I would go at least with a bag rated for 0 degrees F. Better yet, a bag rated for -10 or -20 F. For fill power, I would go with 800, not 650. You'll spend more money, but any money spent on the right sleeping bag for the conditions is a small price to pay. Brand wise, I would be looking at Marmots and Western Mountaineering. We have a couple TNF bags for light conditions in summer and spring, but when it counts, the serious bags are all we would ever consider bringing out. Hope this helps.

Light weight, warm and durable

  • Familiarity: I've put it through the wringer

I've had my BK for more than 35 years. It's light weight; kept me warm on nights when my water bottle froze solid; and it's still going strong. Perfect 3.5-season bag for backpacking in the southern Appalachians.

Great bag...

  • Gender: Male
  • Familiarity: I've used it several times

I love this bag. I have always owned synthetic bags because they were cheaper, but after owning a down sleeping bag I will never go back. Not only is this bag light, but it is like an oven. I have had temperatures in the teens several times with only a base layer, and have never felt cold. This bag also packs down to around 9x10 in. The only noticeable problem that I have encountered is that it looses plums almost every outing. I have never owned a down bag before, so I'm not sure if that is normal. Other than that this is a great bag!

Great bag...

I am highly allergic to feathers and down....

I am highly allergic to feathers and down. What do you recommend that is just as good as this bag but hypoallergenic?

It is what it says it is.

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

It's light, it's warm, and it's comfortable. I slept out for a couple of nights in this bag to test it out. The system used: a small tarp to keep precipitation off of the face, a sleeping pad, and an old military bivy bag. The first night was in the thirties (F) I believe. The bag was soooo hot that I had to unzip it from the bottom to stick my feet out and had to have my head outside. This was in less than a base layer. It felt like it was 100 degrees! Everyone said it had been 30 degrees, so I must believe them. The next night the temperature was around the 9-12 degree F with the windchill at 3 degrees F. I was warm in just a base layer. I slept comfortably through the night and did not even notice that an inch and a half of snow had fallen on my bivy sack that night.

What is the coldest temperature anyone has...

What is the coldest temperature anyone has used this bag in and stayed comfortable?

Responded on

That is somewhat of a subjective question. I would say it is ok down to 10-15 degrees F if you run a relatively normal body temperature or just dress appropriately for the evening.

Amazingly packable and light.

  • Familiarity: I've put it through the wringer

I love this Sleeping bag, and find it perfect for three season usage. It's simple, ultra light, and my go to sleeping bag for everything but winter conditions. I'm a huge fan of full zip bags because you can use them in warmer weather as a blanket.

I need a sleeping bag for mountaineering...

I need a sleeping bag for mountaineering and winter camping and so,i'm to choose between the Blue Kazoo and the Superlight.I'd just like to know if the Blue Kazoo's 15F rating is reliable(because the tag inside the bag says the comfort temp is 28F) .Thanks in advance

Best Answer Responded on

A sleeping bags rating is typically a low temp where it will still keep you warm, but not a comfortable warm. If your going to be sleeping in the 15 deg range, look into a zero deg bag or lower to give you a good comfort level. Regardless of which bag you purchase, I recommend you also get a sleeping bag liner. It will add some warmth to the bag and will also protect it's inside from dirt and is easy to clean. Also be sure to have an adequate sleeping pad for cold ground/snow.

trying to figure out what side the zipper...

trying to figure out what side the zipper is on....if I am on my back in the back....I want to reach across my chest and unzip the back from my left side?....which side would I speck for the zipper?

Responded on

You can select either left or right side zipper when you order. If I'm reading your question correctly, you want a left side zip.

Ok bag but there's better choices

This bag is good for early spring or cooler summer nights but I feel that it does not meet the posted cold rating. I used it in a van one night it was in low 30's and I was cold all night. It does pack small enough for most peoples needs it also zips into other TNF bags my gf and I would zip ours together she had the cats meow. I just feel for the money there's better choices.

Do you have both left and right zip in...

Do you have both left and right zip in regular? Or recommend a combo similar to this for my wife and me?

Responded on

Yep, they do have both left and right zip in regular. A good alternative I suggest is the Marmot Sawtooth 15 Degree bag. Either way, you can't go wrong.

Are there two versions of the Blue Kazoo?...

Are there two versions of the Blue Kazoo? The BK with 650 fill down isn't on The North Face website. TNF lists only one version with 600+ fill. And the pics here and on TNF show slightly different bags, one with an exterior "650" label. Anyone know what's up?

Responded on

Backcountry has received the new version, with 650 fill down and a number of other updates (the new hood design is awesome!) and the TNF website still has the old style, with 600 fill down. TNF will likely update their site soon.
