EN 13537 (or EN13537) is a European standard designed to standardize the temperature ratings on sleeping bags manufactured and/or sold in Europe. As of 1 January 2005 a CEN criterion came into effect covering the testing and publication of temperature ratings for sleeping bags. The new criterion differs from the standards that existed formerly.
So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog”, is the resistance that will maintain a temperature difference of 0.1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.
A sleeping bag's test rating is based on a person who is wearing long underwear, socks and hat, and is sleeping on an insulated pad with an R-value of approximately 5.5. [ citation needed ] There is no standard measurement rating in the U.S., so a 20 °F (−7 °C) bag from one company may not provide the same warmth as a 20 °F (−7 °C) from ...

Essentially, it is just the top half of a sleeping bag. Because a sleeping bag's underside is compressed, it loses its insulating properties. A TQ cuts the unnecessary material to save weight and fabric. The TQ/UQ sleep system is not only warm, but each quilt packs into the size of a grapefruit, or smaller, depending on temperature rating.
