Moira is a comprehensively conceived clothing system; it's developed starting with the fibre itself, continuing with the thread and combined fabric, all the way to the finished products. It is based on the patented Moira TG 900® fibre, which has a cross-section of a five-pointed star. Increasing the fibre's circumference significantly improves its "performance", meaning its ability to draw moisture away from the body while maintaining an optimum temperature.
The special construction of the fabric allows wearing several types of layers on top of one another according to the climatic conditions, thus increasing its effectiveness, or in other words its functionality. The individual layers work together to draw moisture away from the body while regulating heat as a whole. Thus when wearing light Moira clothing you can achieve high physical performance even under extreme climatic conditions.
