For outdoor thermal comfort studies, you may want to consider using a wind chill meter. A wind chill meter is a device used to measure air temperature, wind speed, and relative humidity in order to determine the effect of the wind on a person's comfort level outdoors. It is an invaluable tool for conducting thermal comfort studies outdoors, as it can help to identify areas that pose a risk for discomfort or even hypothermia.

Thank you for your answer Hamidreza Babaeyan, can you suggest a specific material? with brand name and all?

Be aware, that most comfort models do not support outdoor conditions. Temperature ranges, humidity ranges, air velocity ranges (and more parameters) are usually restricted to indoor conditions.
