Western Mountaineering Kodiak MF Sleeping Bag

Jump to: Our Verdict / Features / Specifications

The Kodiak sleeping bag is extra large in every sense – with lots of room to accommodate larger people or just those wanting more room. It also comes in a 7` length.

Western Mountaineering says

Wasn’t it the Big and Tall Gazzette, that called our Kodiak the XL (or excel?) of sleeping bags? This 0° mummy bag has a full 66″ of shoulder girth and 41″ of foot girth to fit any bear sized person. 30 oz. of down fill this bag with 7″ of loft and the continuous baffles keep the bag versatile as the weather changes. Both the draft tube and full down collar are 3-dimensionally sewn and amply filled with down. The MicroLite XP™ shell makes this bag stand firm against any weather. All this with a total weight of only 2 lbs. 12 oz. No matter what your size, we have a bag to fit! The Kodiak is also available in 7′ lengths!

Our Verdict

Western Mountaineering down gear has an awesome reputation in the US and that reputation is beginning to build on this side of the pond. Very high quality materials design and construction results in the lightest bags available for a given warmth.  

An example of their attention to detail is their quoted 850+ fill power down used in all their bags: WM quote this figure even though their down generally gets higher ratings in official tests this is because they feel that the official pre-testing preparation enhances the down quality!

The Kodiak sleeping bag is extra large in every sense – with lots of room to accommodate larger people or just those wanting more room. It also comes in a 7` length.

* Western Mountaineering state: ‘We independently verify own temperature ratings through our own testing, customer feedback and design knowledge. Most of the items in our catalog we have been making for years, which means we have lots of prior knowledge from everyday consumers on what ratings are accurate. We have also EN tested our bags. In every case the EN rating is lower than our posted rating. This means our ratings are more conservative. We do this to ensure that almost everyone will be happy in our bags at the temperature we publish.’
