2.1 What is what?
1 Slide-in pockets with PCM elements
2.2 Functional description
The cooling elements made of PCM (phase change material)
are integrated in the comfort vest to absorb the body heat of
wearer.
When donning the comfort vest, the PCM is in a solid state of
aggregation. As the ambient temperature rises, the PCM
absorbs thermal energy and changes to a liquid state of
aggregation.
Depending on muscular effort and ambient temperature, the
cooling effect will last up to two hours.
2.3 Intended use
The comfort vest is a piece of clothing which reduces the body
temperature of its wearer in hot environments as well as during
physical work which causes perspiration.
2.4 Limitations on use
The comfort vest is not to be considered as personal protective
equipment. The comfort vest offers no protection against fla-
mes, stabs, blows or similar dangers to the wearer.

If necessary, restore operability as follows:
1. Heat the PCM elements at +32 °C up to +40 °C, until the
salt crystal mixture is entirely liquid.
2. Put the PCM elements on a horizontal, even surface,
stroke until flat and store for at least 2 hours at less than
+20 °C or at least 30 minutes at +8 °C.
The PCM elements will then have regained full operability.
