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 4 out of 5 by from Warm and packs down small for travel. This is a great 3-season sleeping bag if you know how to use it. I say IF because after reading some of the other reviews here some people were obviously disappointed and I’m not convinced it was the bag that was the problem. I’m in Canada and just got back from a week of camping in a bit of sun, a lot of rain, snow flurries and night temperatures cold enough that the overnight ice on the ground didn’t melt till noon that morning. So is the bag cold? No sleeping bag on the market can be used in cold temperatures without an insulating pad underneath it, a pad suitable for the temperatures. Attempting to sleep with no pad or an unsuitable pad will result in the heat being sucked out where the bag is compressed under you. Letting the bag get wet will also seriously compromise the insulating properties of the down. And believing that you should be toasty warm, buck naked at the temperature limits of the bag is just naive. This bag was used in some serious rainstorms in a Hennessy 4-season hammock with an alpaca wool poncho doubled underneath as a sleeping pad in temperatures as low as -5C this week. That is colder than the comfort level specified for the bag and I did sleep with thermal socks and fleece leggings and top. And because of the high humidity conditions and to limit issues with condensation overnight I did close off most of the hammock mesh with my rain gear (under the tarp). I slept comfortably for 5 nights. There’s no such thing as a 4-season sleeping bag. One insulated enough for -40C would be too warm to use in summer and a bag that is light, packs down small and is ok for summer use is useless in the winter unless doubled up inside a second bag. This one is a nice compromise and it’s coming up 7 years old now so it’s stood up well. Stores nicely in a 10 litre dry bag and can be compressed down to 5 litres for travel to permit clothing to be added to the bag for travel.

Rated 1 out of 5 by from Too Cold Camped in a tent between 2 and 10 degrees but was never warm. Extra blankets, thermals, tracksuits and socks couldn't make up for the poor performance. Maybe a good spring bag for +12 degrees. Definitely not the claimed 2 degrees for women, -3 for men. Kathmandu refused to refund or deal with the problem. Submitted my complaint to consumer protection and received a full refund.

Rated 5 out of 5 by from Great for hiking in cold weather. Comfy as. Bought this a couple of months ago during the pandamic to do some hiking in the winter and this sleeping bag held up great. Staying on the river under 0 Degrees with frost everywhere and i was sweating (I was in my tent as well) but had to chuck out the sleeping bag liner as it was not needed. Also, only weighing just over 1 kilo, it was a great addition to the bug out bag without making the bag too heavy. Worth every Cent

Rated 3 out of 5 by from Not warm enough unfortunately I bought this sleeping bag last year, for camping in NZ. It seems even worse this year than last year as I had to add arctic socks on top of my 1 base layer merino singlet, then a long sleeve thermal and a hunting and fishing jumper overtop. All just to be comfortable through the night. I will buy a new bag but probably not from here this time.

Rated 2 out of 5 by from Not so good kathmandu I took this sleeping bag on the overland track in feb. Its supposed to be rated to -3degrees. However i had to sleep with thermal underwear, socks a silk slip sheet liner, and a thermal insulation mattress and was still freezing cold. Dont trust the temp rating on there sleeping bags. It may cost you your life. Very disappointed. I later purchased a mountain design sleeping bag for the same price. Much better.

Does the zipper go all the eat to the bottom?

Asked by: Green1
There are two zippers, so one goes the length of the bag and then there is a second zip that goes along the foot box of the bag.
