The bears have it figured out.

Not only is the Western Mountaineering Kodiak Gore WindStopper Sleeping Bag big enough to fit a bear-sized camper comfortably, but it's also warm enough to keep one hibernating all night long. Constructed with just over 30-ounces of lightweight, 850-fill goose down insulation (complete with seven-inch loft), this bag assures a toasty night's sleep for backpackers looking to cut weight when adventuring in the frosty outdoors. Not to mention, the Gore Windstopper fabric, combined with the down-filled draft tube, prevents frigid, howling winds from piercing your cozy slumber. And when you rouse from a dreamy night's sleep in the morning, toss your bag into the included stuff sack, easily store it in your pack, and hit the trail towards your next site.

Beast in the high/back/cold country

I've put it through the wringer

This product is made in the USA and is outstanding. Having owned my GWS Kodiak for several years, I would not trust another bag. Price, quality, durability, piece of mind - all extremely high. Just used this during a few nights out and coupled it with my Zpacks Bathtub Groundsheet sans tent. The GWS takes a few uses to earn your trust, but I prefer going lighter now when rain is not an option. When in Utah, this combo was easy to use for backcountry tours and nights out during the winter. Plenty of girth in the shoulders for larger guys/gals and/or the ability to twist and turn at night. Recommend getting a longer size and putting touring liners, layers, socks, bottles, gas canisters down there to dry/stay warm at night. With 30oz of high quality down, this bag lofts to 7 inches. For just over 3lbs you get a lot of comfort and insurance when out in frigid temps. I tend to sleep very cold during the winter, this bag has never let me down. Generally pair with a partial closed foam (Z Rest) for shoulders to hips and a NeoAir X Therm. Have slept comfortable in/outside a tent well below 0. Recommend either a buff or balaclava if it is snowing/sleeting just to keep it off what is left of your skin once you cinch down the collar/hood. At 6'2, I really appreciate the extra space in this bag, if smaller you can expect plenty of room to side/stomach sleep and/or layer to stretch the temp rating. Pair this with a large stuff sack (recommend turning inside out if going with a GWS model) and there is no excuse to lug around a heavy tent. Light mist/frost/rain have not soaked through this bag, have also had lots of snow fall throughout the night without any wetting out. In the a.m., this bag dries out really quick if you have a little sun. If not, again, stuff inside out to aid in compression and keeping the insulation as dry as possible. Pair with a megamid and you have a solid winter set up. Key features include: snag free zippers, huge draft tubes, thick/firm seam tape on both sides of the zipper, cinch cords on the hood and plenty of insurance for any 4 season excursion.

Thanks for this review, Matt! This is awesome :)

Kodiak sleeping bag

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

Got this bag for a hike in Glacier. i am a thin person and tend to be a cold sleeper. I have tried the military Modular system in 25 degree temps in the smokies and still slept cold. i have also used the north face cats meow and slept cold in 30 degree weather at mount rogers. I have not tried ikodiak in cold conditions yet of anything under 40 degrees. That being said it is a quality made sleeping bag . i have even used it as a blanket watching movies in the winter in my house. i enjoy the feel of the fabric which is very comfortable across the skin. it does pack very easly. There is no perfect sleeping bag. i purchased this bag because i read every review and could not find a bad review of the company except maybe the price. i will up date later on using i t in cold conditions. Charles

Thank you for the review, Charles. Western Mountaineering does make the best bags, and it's easy to understand why there are so many positive reviews. The price is a reflection of it's quality and also that it is made in the USA, from it's beginnings in 1972. Same owner / founder!! Great company! Leta Western Mountaineering Rep

Simply The Best !

I've put it through the wringer

Western Mountaineering sleeping bags are absolute works of art. No other company that makes sleeping bags comes close to Western's quality and attention to detail. As example, the protective heavier fabric membrane on the interior down draft flap. This protective membrane makes it almost impossible to snag the draft flap with the zipper when opening and closing of the bag. What a great feature. Once you own a Western Mountaineering sleeping bag it is almost impossible to go back to anything else. They are just that good.

Great bag

Typical WM quality. Light and warm. The picture is the Sequoia. I have the MF version. The image on that is correct. You ought to correct it.

Hey Paul - thanks a bunch for the review. This is the same picture of the Kodiak that is on the Western Mountaineering page. So I actually think both need updates. Yes, the Kodiak is a wide mummy, but still tapers more than the image shown here. The is semi rectangular, which, as you point out, is the Sequoia. Good eye! Many thanks, and enjoy your Western bag!

Ethan, thanks for the write up! I have been with Western mountaineering for 15 years as their rep and I can tell you that these guys are as authentic as it gets. US made, the best down available, impeccable stitching, and starting now, Western will have a "signature tag" on each bag for the signature of the amazing people who constructed the bag - so, so cool. Really gives the bag an artisan touch. You will start to see that coming out next spring or sooner! Reach out if you have any questions! Leta Western Mountaineering Rep

Hi so im looking to buy this bag for sheep hunting but I have one issue and that is the stuff size. Would a compression sack help to get the dimensions of this bag down? If so what would the dimensions be? Thank you
