2-Season Sleeping bags

Many factors influence the experienced warmth of the sleeping bag.

Haglöfs sleeping bags are tested according to the common industry standard called EN 13537. This standard gives approximate temperatures at which a normal man and a normal woman should, respectively, be able to sleep comfortably without being cold. Many factors influence the experienced warmth of the sleeping bag, e.g. what type of sleeping mattress you have, what type of tent you have and how many people share it, what you wear, the outside wind and weather conditions and so on. Your own energy level and fluid intake will also affect your ability to stay warm.
