All the warmth without the weight.

The Western Mountaineering Kodiak MF 0 Degree Down Sleeping Bag is a backpacker's dream. This mummy bag uses lightweight 30-ounce 850+ down fill insulation that provides a full 7 inches of loft. While the down brings the warmth, the sleeping bag weighs in at a modest 2lb 15 oz (regular size) so it isn't also bringing the weight. Its MicroLite XP shell is surprisingly durable despite its lightweight appeal. It's also very breathable and highly water-resistant so you get a restful recovery during the cold nights of your backpacking adventures. Its abrasion-resistant taffeta lining won't tear up if you have to sleep with some gear in your bag.

Western Mountaineering sewed the Kodiak's full-length down collar three-dimensionally so your neck remains snug and warm all night long. The draft tube also has a three-dimensional design to ensure you stay warm. The 5 1/4-in spacing and continuous baffle construction allows for easy compressibility and packing.

This bag will not disappoint!

Familiarity:
I've put it through the wringer

Since I live in Alaska this bag has been used at temps from 0 to -33 below zero and it never disappointed me. One trip at -10F below it was almost too warm. I was only sleeping in socks and lightweight long underwear tops and bottoms. I did not need to cinch the hood as I was afraid of overheating. Have used this bag at -33F below and it kept me warm as well but I did have on WM don pants but only two long underwear tops. I considered the WM Puma bag but I went with the Kodiak since I liked to travel as light as possible. The 0F rating on this bag is pretty conservative so I would almost bet that the Puma would be good at just about any temps humans adventure in.

Unreal warmth

Familiarity:
I've used it several times

Loved this bag from the second I opened up the box! The attention to detail, the stitching, the hand written label, the quality of the material...all amazing. Bought this for some winter camping and it was worth every single penny. While the temps never dropped to the zero range this bag more than met my expectations and absolutely blew me away. Simplicity, light weight, extraordinary warmth and performance make this bag a winner. Oh and the loft on this thing is insane, they were not kidding about the 7" of loft!

Thank you for the review! Leta Western Mountaineering Rep

Warm finally!

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

I am a very cold sleeper and a 15 degree bag just doesn't do it for me in 20F and 30F degree weather but this bag was very warm and comfortable. The loft is amazing and I felt very cozy all through the night. It was a little difficult fitting it into my compression sack but so worth it!

Thank you Deborah! Enjoy your Kodiak! Leta Western Mountaineering Rep

Lofty. Light. Perfect.

Ok, I admit it. I'm a WM junkie. I can't help myself! It's only recently that I discovered and started buying this brand. My son has had a Kodiak for more than 12 years. He's an avid outdoor enthusiast, but I never really tuned in to his bag which he bought while in college. But a few months ago, I bought him some WM booties and a pair of Flight down pants for Christmas. I was so impressed with the quality of the down, materials and build quality, I bought another set of both for myself. I just bought this bag in the 7' version. I'm 6'3 and 200 lbs, so I could have bought the 6'6 version, but wanted the extra room. I can wear my down Flight pants, booties and my HUGE Mountain Hardwear Absolute Zero parka ( "Big Orange") if I need to when the temps get REALLY cold, say well below zero. This bag is so lofty and warm! The zippers have a wide taped area to prevent snags while zipping. I can zip up to the top, secure the hood around my face as needed-something I've had trouble doing easily in my other bags. I'm a bit claustrophobic but this bag solves that nicely. It is really roomy around the shoulders, and then tapers down perfectly to the footbox. The Micro Fiber shell is so light, it allows the down to loft up to its max. Also, although I've yet to try it, the baffles allow you to move the down from top to bottom (or vice versa) for different ambient temperatures. Also, it's really nice to buy an American made product that is, in my estimation, head and shoulders above most other brands. I spent more time researching this bag than I did buying my last car. Seriously! But although I like Feathered Friends too, I settled on this bag. WM offers the 7' version in this model without a special order and backcountry.com had it in stock. You will be extremely happy if you purchase this or any WM bag. Expensive, but worth every penny. Also, a shout-out to backcountry.com for being a world class retailer. Customer service is unparalleled in this segment. They shipped 3 hours after I ordered, and I had it in New England 2 days later! If you're like me, you want your order fast and backcountry.com has a new warehouse on the east coast to facilitate things. Congrats ALL around!!!

Paul, Thank you so much for your stellar review. I have repped Western Mountaineering since 1998, and cannot say enough about the company. Gary Schaezlein has owned it since the day he founded the company in 1970. He still runs the ship today, making absolutely some of the best down products you can find. I would like to send you a sticker from Western... They are hard to come by, but I have one for you! Would you please reach out to Backcountry and get in touch with Ben Rabinowitz - he is one of their expert GearHeads. He will get you in touch with me, OK? Tell him Leta said so! :-) Many thanks, Leta Western Mountaineering Rep

How stuffed can this get

Familiarity:
I've used it several times

I was wanting this bag to fit well into my backpack with the new stuff pods. If anyone is wondering about this fitting it does. The zipper may bite the bag with it being so stuffed but it works with the hyperlite large 4400 stuff pods. I wouldn't leave this sleeping bag in this pod mote than a day however however. May ware the fluff out.

Great winter bag

Familiarity:
I've put it through the wringer

I bought this bag specifically for winter camping. I own a lighter 30 degree bag from Western Mountaineering which works great. I used this bag on a 8 night ski mountaineering trip were the temps definitely dropped below 0 F. It compresses down well, although I had to use a separately purchased compression sack. I stayed warm the whole trip. The hood closures are simple, but effective. These guys make great bags.

Can't Wait to Test This!

I am very cold natured and wanted to upgrade my sleeping bag. I wanted the best of the best and Western Mountaineering delivers. The bag is high quality design and craftsmanship. I can't wait to test this in the field. I am sure I will be sleeping warm all winter long.

Hey sgb, please let me know how it goes and send some pictures! You will LOVE this bag! Leta Western Mountaineering Rep

Finally, I think I found the right bag!

Familiarity:
I've put it through the wringer

I bought a big agnes 0 bag and Qcore pad thinking that was going to be the way to go for my back pack archery elk hunt in Co. I sleep cold and claustrophobic so not just any bag works for me, unfortunately. Though roomy for my 6'2", 200lb frame, too many cold spots in the BA bag, especially at the pad's edges, on a 28* test night. I had to return it, disappointed. The Kodiak MF, was pricey, yes! But my experience on an uninsulated Klymit pad at 11000ft on a couple 27* Sept nights in Colorado was what I had hoped for. It's easily vented at the legs or great for burrowing. I've even week-long hammock camped with it down to 30* most nights (july Co Mtns) with only a sliver of that reflective bubble insulation from home depot. I can jam this bag into a10L Outdoor Research Airpurge Dry compression stuff sack. BTW - BackCountry really took care of me on my exchange. Like their service! They've kind of become my specialty sport gear outfitter!

This is good to hear, I'm 6'3" 225, recently returned my BA bag to a camping chain that touts "no hassle refunds for any reason", and hassled the crap out of me for my return. My 15 degree BA bag looked nice, the sleeping system was nice, but I was cold all night in 37 degrees. I found WM out of internet search for a bag with a true EN rating, the guessing is frustrating. I plan on sliding into an Alpinlite, and this bag next week and purchasing the better fit of the two. I hear the En ratings on these bags are excellent, and very accurate.

Uncompromised Excellence

Familiarity:
I've put it through the wringer

From a small independent company, WM delivers an outstanding product from their factory in San Jose, CA. They pride themselves in the highest quality product, material and customer experience - all right here in the USA! I have been using the Kodiak GWS for a few seasons, outstanding product. the GWS varies a little from the MF model, basically shell weight. The GWS version is a perfect/true 0 degree bag that I have stretched into -10 range w/out issue. I am 6'3" and needed a long/broad bag to accommodate extra clothing and touring liners. at 7', the long is 67x58x41 with 34 oz of the highest quality down available. Weighing in at 3.8 lb's, this bag can easily be compressed into a compression sack and alleviating space concerns found with most winter bags (try stuffing a GWS bag inside out to get more compression and simplify the process). I have used this bag, on snow, w/out a tent, w a tarp and inside a 4 season tent - excels in all situations. The GWS shell sheds precipitation and is windproof. A friend and I were skiing off Wheeler Peak last year and temps were definitely below 0 - basically wore my mid-layers at night and was plenty warm. That said, there is more than enough room to wear down clothing and increase the temp range. Mind the size, this is really well suited for broad shoulders. Details: draft tube and collar are down and capped with Gore's Windstopper fabric (GWS shell). I have other MF shelled bags from Western and they do a very good job with moisture, but love the options with the GWS shell. Not for shallow pockets, but an outstanding product that is well worth the price when you need to rely on a winter bag. WM also offers overstuff options if you need to pack a little extra down into the foot box.

I have a Kodiak MF roughly 6 years old love the dimensions as I sleep on my side and like to spread out. This bag is roomy and warm however my experience with the MF water repellency has been pretty bad. Every time I used it, condensation soaked the fabric and on one occasion actually penetrated the fabric soaking the down. I also have the badger with gore WS just throw a liner in it and no problem. So for me unless they have changed the MF fabric or DWR treatment if I go for another 0 degree bag or lower I will have to suck it up and pay for the Gore WS fabric.

1. I’m a 5’11” heavily built male. Should I go with the regular length? 2. My single wall ultra light tent sometimes sweats profusely in moist and cold conditions. If it’s very cold I wake up with frost on the bag. That being said I generally avoid precipitation when planning a trip. Do I need the Gore Tex?

Is this down hydrophobic?

Hey Matthew, it isn't. Western Mountaineering doesn't do hydrophobic treatments on any of their down-- their position, as it has been related to me by our rep, is that they are certainly interested in the technology, but they have not yet completed any in-house testing for longevity or reasonable short term performance in a wide enough range of conditions to make a decision on whether or not it is superior to the down they're currently are sourcing that is not treated. My understanding is that they are currently testing hydrophobic down in a few different products. If you'd like some help finding the perfect sleeping bag to fit your needs, feel free to contact me directly! llabar@backcountry.com or 801-736-6399.

Hey Matthew (and Lara), Lara, thank you for the answer. We are testing the hydrophobic down only to show that it is, in our opinion, negatively affected by this toxic synthetic treatment. The aspect that makes down awesome is it's natural properties of loft. When you apply a treatment to this product, you reduce its loft and its ability to move your body's heat. It's the same reason that down insulation feels more comfortable than synthetic insulation in regulating body heat... and then you apply a synthetic treatment to it? No thank you! So although Lara is correct, we are testing it, we are not doing so with ANY desire to use this coated down. The other reason why we stay away is that no one really knows how long it lasts... we don't want to give you a false sense of security that your bag or jacket is "waterproof" when any coating eventually wears off. So, Western's take on this hydrophobic down - we won't use it, for lots of reasons, some that are listed above. If you are in wet conditions, use a tent, go with our Gore Windstopper products, and treat your bag right. And I PROMISE you. It will treat you right in return. Thank you for the question, and to Lara for the answer! Leta Western Mountaineering Rep

I stand corrected. Thanks Leta!!! :)

I'm 5' 115lb petit size, and I really love what I hear about WM. But I'm very worried that even the SMALL size might be too big for me. I have a regular width shoulder for 5' woman, and this bag's girth is 66" around shoulder. Would that be too wide for me? And is this bag too long for me? Too much air moving around killing the great temp rating?

Hi there - it's Leta with Western Mountaineering. You are exactly right. I would not recommend this bag for you - too big! What you CAN do from Western is get the 5'6" Antelope, with a 62" girth at the shoulders. That is 5 degrees. OR, if you want more warmth, go with the Western Mountaineering Lynx at -10 degrees. They make it in a 5'6" with a 61" shoulder girth. Backcountry.com Gear Heads can order that for you. I hope this was helpful! Leta
