Kelty has always tested sleeping bags to make sure that their customers are warm and comfortable on their adventures. Now they`ve adopted the European Norm (EN) 13537 test process which provides a standardized comparison method for all sleeping bag brands so that it is easier for you to choose the right sleeping bag for your needs. The two temperature ratings listed are Comfort and Lower Limit. Comfort is defined as the temperature that a standard woman (60 kg / 132 lbs) will be comfortable at versus Lower Limit which is the temperature that a standard man (80 kg / 176 lbs) will be comfortable at.
