GUARANTEED TO KEEP YOU WARM
Thermo-Plus is Levels certification and guarantee for outstanding insulation and heat retention of the natural warmth of the hands even in the worst climate conditions. Level created a machine to test the gloves in a series of extreme weather conditions. The results, collected in an efficiency index, report the gloves’ thermicity values. Thermo-Plus products values aim to be at least 30% higher than standard gloves’ ones.

SCIENTIFIC TESTS TO GUARANTEE THE THERMOPLUS CERTIFICATION
The choice of the appropriate material for the construction of gloves is of fundamental importance in order to achieve ergonomic comfort and high thermal insulation. The thermal insulation and the moisture management of gloves made of different materials have been tested both in a climatic chamber and in outdoor conditions using wireless sensors combined with infrared thermography. The results obtained show substantial differences in terms of thermal comfort between the gloves in the same environmental conditions, proving that level provides the best thermal comfort in all of its products.
The thermal image #1 shows no leakage of heat on the outer surface of the glove thanks to its excellent insulation. Absence of red color.
After removing the glove, the thermal image #3 shows the hot hand thanks to the excellent glove insulation. Absence of blue color.
THERMAL BEHAVIOUR – EFFECT OF MATERIALS ON THERMAL COMFORT IN REAL AND SIMULATED SKIING CONDITIONS
Thermal insulation is one of the most important factors for a proper protection against cold. Since hands have a large surface area compared to their volume and a small muscle mass, they both tend to be much more sensitive to cold exposure with respect to other parts of the human body (kuklane, 2009). It has also been reported that the feeling of cold discomfort into the hands will dominate even if clothes with proper insulation are used on the rest of the body. The hands are comfortable when the skin temperature is about 33 °C (91.4 °F) and the relative humidity next to the skin is about 60%. The feeling of cold starts at temperatures around 25 °C (77 °F), while discomfort from cold is noted at temperatures below 20-21 °C (68-69.8 °F).
Skin temperatures measured during the test in a climatic chamber at -10 °C (14 °F).
