The classic - especially for hunting

The warmX-undershirt is the classic in our warmX collection. Two warming zones are placed around the kidneys. In this region the body is highly temperature sensitive and therefore must be warmed right there. The subjective feeling of „being warm“ is best when the kidneys are warmed. Furthermore also feet and hands won’t cool down that fast, because the blood of the body runs through the kidneys and is warmed up there.
To achieve an optimum thermal transfer it is essential for the warming zones to be preferably close to the skin. That fact was considered of course during the design of the cut. So please choose same size as you would if you bought a normal pullover.
