Today we are looking at a range of 4 season sleeping bags from UK businesses. All of the sleeping bags featured in this article are mummy sleeping bags because most 4 season sleeping bags are mummy shaped as they tend to be warmer than rectangular ones.
Mummy sleeping bags aren’t for everyone though. They are very close fitting to minimise the amount of dead space, and therefore air, that your body has to heat up – it’s mainly this that makes them warmer. Also, the fact that they taper in towards the feet, means they tend to be lighter than their rectangular counterparts, simply because there is less material. The down side of this is that mummy sleeping bags can be claustrophobic to some as there isn’t much room to move once they are zipped up. If the idea of being trapped in a narrow sleeping bag causes your palms to sweat, you need to check out our article on Camping quilts available in the UK. Camping quilts provide warmth without the straight-jacket effect. Another option is to go for a modular system where you use something like a camping quilt alongside a blanket to provide the warmth you need.
Are sleeping bag temperature ratings accurate?
It depends. You might find you need to take the manufacturers’ temperature ratings with a pinch of salt. The more expensive brands tend to be more accurate, but with a cheaper sleeping bag you might find the temperature comfort rating to quite a few degrees C out. So for example, if it says the comfort rating is -2 degrees, you might find that you get cold in the bag at about 3 or 4 degrees. The reasons for this vary wildly though. Yes, the sleeping bag manufacturer could just be being over optimistic, however, factors like whether you sleep hot or cold, what you’ve eaten, what your weight and health is like, what your sleeping pad is like (is it insulated), what you wear in your sleeping bag, and what you’re sleeping in (tent or bivvy, for example) all greatly affect your warmth in the night. Only experience will tell you what works for you as it tends to be really subjective.

So that’s our range of 4 season sleeping bags from UK businesses. We have provided the details offor one sleeping bag from each brand. Some of the businesses have a number of 4 season sleeping bags, so it may be worth having a check on the manufacturers’ websites.
As mentioned, a mummy-shaped 4 season sleeping bag can be quite claustrophobic, but if you’re not bothered by that then this style of sleeping bag will probably provide the warmest and lightweight option for winter camping in the UK. If you’re planning on wild-camping up in the mountains or backpacking any sort of distance, then the warmth to weight ratio is obviously a consideration.
It’s worth mentioning too, that if you’re really happy with your 3 season sleeping bag and you don’t have the budget for a 4 season bag, you can make your 3 season sleeping bag suitable for winter use (depending on the location and weather of course) with the use of a blanket or a lightweight sleeping bag liner.
