Coletherm®: Exclusive to Coleman®, Coletherm® is a synthetic material with hollow fibres that create pockets of air. The structure of the hollow fibre filaments traps a greater amount of air, improving the loft and temperature performance of the sleeping bag. The air pockets retain your body heat and reduce convective heat loss, keeping you warmer. Machine washing does not affect its performance. |

Coletherm® Micro: Coletherm® Micro has been specifically created for Coleman®. This high performance synthetic insulation is very light and compressible, resulting in extremely compact pack sizes for easy carrying. It is a bonded micro fibre insulation that works by trapping air around the fibre for a more effective performance. It offers a great heat to weight ratio and has reduced fibre migration, so no cold spots. |
Performance testing
Independent temperature testing
For your comfort and peace of mind, sleeping bags are tested at independent testing laboratories to determine their temperature ratings and to comply with the temperature rating protocols of the European Standard (EN 13537-4.3.3) Mannequin Methodology.
However, when choosing a bag, always bear in mind that temperature ratings are given as a guideline only. Each sleeping bag user reacts differently according to the following factors:
- Physiology of the user – male or female, level of tiredness, age, diet, body mass and clothing
- Weather conditions
- Ground insulation
Apply common sense when making your decision, taking into account the likely conditions of use and your individual requirements. Inexperienced campers should always use the Comfort temperature.
Materials testing
Sleeping bags are subject to stringent materials tests before production commences. Fabrics, fibres and zips are all put through their paces to ensure that the products you buy have a long lifetime, are cosy and warm and give exceptional, safe performances time after time.

Temperature ratings
The definitions provided in the European Standard are:
- Comfort: Temperature calculated for a standard woman* who is not feeling cold (no shivering) and in a relaxed posture.
- Limit: Temperature calculated for a standard man* in situation of fighting against the cold (posture is rolled up inside the sleeping bag), but in thermal equilibrium and not feeling cold (no shivering).
- Extreme: Temperature calculated for a standard woman* in a situation of high cold stress and at risk of hypothermia. *
Standard woman: 25 years old, 60kg, 1.60m, 1.62m2 *
Standard man: 25 years old, 70kg, 1.73m, 1.83m2
