Abstract
Aim: The primary goal of this study is to evaluate the thermal comfort of a typical riding helmet by incorporating commercial phase change material (PCM) (CR+28).
Method: In this project, CR+28 with a latent heat of 180 kJ/kg was employed, with a thermal conductivity range of (0.5 – 1.1) W/m-K, and a phase transition temperature range of 26 to 28 °C. Standard riding helmets were used for group 1, while group 2 consisted of standard riding helmets with CR+28 incorporated as a sustainable PCM. There were 20 samples in each group, with the sample size calculation performed using G-power with a power of 80%, α = 0.05 per set, resulting in a total sample size of 40.
Results: The addition of CR+28 to the helmet increased thermal comfort by 9.19% when compared to the standard riding helmet without CR+28. According to statistical t-test analysis, there was a significant difference in the mean-variance of thermal comfort between group 1 and group 2, with a p-value of 0.001 (p < 0.05).

Conclusion: Within the constraints of this study, it is evident that the addition of CR+28 significantly boosts thermal comfort inside the helmet.
