Crew Neck Long Sleeve Shirt in White

Developed in Japan, engineered for the American summer. Core Line's proprietary xylitol and erythritol compound draws heat away from your body the moment it builds — more coverage means more cooling contact, working from your shoulders to your wrists so you can stay out longer and push harder.

Clinically tested to lower skin temperature by up to 15°F
Recognized by Japan's Heatstroke Zero Project for heat stress mitigation
70-80% cooling retention through 50 washes · UPF 40+ sun protection
