Temperature rankings are quite crucial items of details to consider when picking a bag. And although mummy and also rectangle-shaped resting bags can cover a wide range of temperature levels, mummy bags are the common designs for the extreme polar temps such as those you would locate in the Andes.
Rectangular sleeping bags are the initial and also most typical form you'll see on the market. I directly don't think there is much of a visible difference in between the fillings nonetheless synthetic fibers will certainly not soak up water and will certainly keep you warmer also if the bag is a little bit wet. A damp down resting bag is very hard to dry out as well as is taken into consideration even worse than having no sleeping bag at all.
If the sleep bags that you are taking a look at have not embraced the EN requirement, do not flip out. You could go by their temperature level measurement. The only difference is that these dimensions are to be used as a guideline just and do not think about the male/female distinction. Obtain a rest bag with added loft and also a reduced temperature level number if you're like me as well as are usually chilly whenever you sleep. The reduced the number, the cooler the exterior ambient temperature level can be where the bag will keep you cozy.
