Mummy bags, with their wider cut shoulders and narrow feet are the most efficient when it comes to weight and warmth. These bags conform more closely to your shape and only require minimal body heat to warm up. They encase you ‘like a mummy’ and may be restrictive and less roomy than other bags.


Semi-Rectangular bags with their tapered foot (more room than the Mummy) and contoured hood are a good compromise. These bags provide ample sleeping space at the torso for comfort.


Rectangular types offer more space and are cooler than others, letting you move easily within the bag. Because of the larger top opening, heat can escape more easily.

Rated 5 out of 5 by from Half price of equivalent quality brands Never get to use it as my darling sweetheart has decided that I can still use my pacesetter and she gets the Polaris.Either bag could be used anywhere on earth as long as the sleeping mat was equally up to the demand of the conditions.

Rated 5 out of 5 by from Excellent bag with great features I own several high end sleeping bags and wanted a cheaper bag for use on camping to save my expensive bags so bought the Polaris as it uses goose down ( not suck) and has a pretty good loft value at 700. So far I have been very happy with the bag and would be hard pressed to buy a top tier bag again considering the performance and value of this bag. My only gripe would be the lack of a compression bag which is really helpful and given the high quality down means the bag can be compressed lot more that with the supplied bag. I bought the Kathmandu compression bag and using that the Polaris can be compressed to fit inside a standard backpack.

Rated 5 out of 5 by from Perfect for Snow Camping in Freezing Conditions I brought this sleeping bag almost two years ago and have taken it on many adventures with me. Because I bounce back an forth from NZ to Canada I have had the opportunity to use it in many different weather conditions. I have used it in -25˚C with a semi-waterproof bivy and I stayed warm and dry throughout the night. Although this sleeping bag isn't the smallest, when you compare this to the conditions it is made for it is totally worth it. Kathmandu, again you never fail to disappoint me :)

Rated 2 out of 5 by from ?????????? How can this bag be so well reviewed is a mystery... Perhaps at the time of sir Hillary it would have been a good one but nowadays winter sleeping bags are relatively waterproof to highly waterproof. This one can't hold condensation. If you have to spend several nights and mornings in foggy weather you'll quickly understand why winter bags need to be highly weather resistant. Pertex endurance which isn't even produced anymore by Pertex, is a breatheable fabric not a weather resistant one. A pertex shield is what's needed on something called an " expedition bag ". The downtech is a joke. Chemicals get easily washed when the bag get damp, and there is no any chemicals which protect down from making balls therefore making of a warm bag nothing more than a simple linen. Obviously it does the job when camping in a large tent on a nice campground. Yet it cannot be used for expeditions unless you're ready to carry several extra kilos for a heavy duty winter tent. Perhaps at the time of sir Hillary, there were sherpas to carry the extra load. Nowadays we have good gear, to minimize weight and maximize efficiency. It's light and warm. Good for a short winter hike when the weather is cold and dry. Unfortunately mountain weather is versatile and at - 15 °C, humidity and condensation are still possible.

Rated 5 out of 5 by from Best Purchase ever! I just recently bought this bag and I am so happy with my purchase! It's defiantly the best sleeping bag that I have ever owned. It lofts up just like the picture and is extremely warm. When it was delivered to me I slipped into it and was very hot almost instantly so it will defiantly hold up in those cold climates! I really like the draft collar inside the bag, and the tightening on the hood to close around your face. When the bag is on sale, it's very hard to find a bag better than this one :)
