4M Long Johns Winter Level 1

The 4M MOIRA Level I underwear set has been developed by MOIRA for the 4M tactical line of clothing. Thermal comfort is guaranteed by the MOIRA Thermon material which draws body moisture away from the skin to the outside.

The brushed surface of the material acts as an insulant by holding a
large amount of air. Thermon has been designed to provide the first layer of clothing in cold environments. When used in low temperatures, it is advisable to wear the Level II set as a second layer, which will significantly increase the user’s thermal comfort even when the outside temperature reaches – 40°C.
