Gelert sleeping bags have been sent to the world renowned Hohenstien Institutes in Germany to conform with EN 13537 standards.
This standard provides a comparison between different sleeping bag manufacturers so that the consumer can evaluate the different temperature ratings. The sleeping bag temperature ratings are as accurate as scientific measurements can be, and can assist consumers in choosing the appropriate bag for their intended activity.
The EN 13537 test is conducted under controlled conditions using a manikin in the sleeping bag that has separate heating zones and temperatures sensors to simulate a human body in a sleeping bag.
These tests give accurate information on the range of utility of the sleeping bag, the determination of a comfort, limit and extreme temperature rating
Sleeping Bag Temperature Ratings
The sleeping bag extreme temperature rating is the lowest temperature at which the bag will perform.
The sleeping bag comfort zone indicates a temperature range making sure campers feel comfortable throughout the night.
Sleeping bags can also be catagorized into seasons. These are a guide to supplement the temperature ratings.
