HeatCrush™ cools your body using your own sweat. When perspiration contacts this performance mesh and micro-jersey developed in Japan, it begins to draw heat away from the surface. As airflow increases with motion, the cooling effect deepens. The response scales with effort.

SATISFY Pro Athlete Max Jolliffe ran the full HeatCrush™ system across the Atacama's altiplano, where there’s no shade or shelter. At this elevation, sweat evaporates before it can cool anything. The fabric pulled moisture in and returned it as cool, keeping him out long after most would have turned back.
