Details of the Soma Cap Light 4.0 Beanie

The new 4.0 generation is the first to offer Retina® ultra-high definition quality for the highest functional accuracy. The result is an ultra-dense knit in which thermoregulating functional zones are precisely positioned and can act with pinpoint accuracy.

Insulating zones prevent heat loss at the top of the head, and the legendary patented 3D Bionic Sphere® system enables adaptive thermoregulation by cooling when you sweat and warming when you freeze. Sweat Traps® trap sweat before it starts to flow and help balance temperature through targeted evaporation. At the temples, the AirConditioningSpot absorbs excess moisture, allowing it to evaporate to the outside while preventing excessive cooling.


The patented, award-winning 3D Bionic Sphere® System stops uncomfortable moisture, the feeling of overheating and the risk of cooling down during rest periods.


Provides ultra-high definition texture, ultra-high impact density and ultra-precise body zoning.


Ergonomically placed sweat traps prevent moisture dripping and provide active cooling. Patented in 22 countries.


Ensures perfect ventilation in cold conditions. Precious heat is prevented from escaping.

Material 90% polyamide, 6% elastane, 4% polypropylene
