Cool Wool: Why Wool Outperforms Cotton in Heat

Wool regulates temperature because of fibre structure, not marketing.

Merino fibres absorb moisture vapor before it becomes sweat. Open weaves allow airflow. High-twist yarns prevent collapse in humidity. Cotton absorbs moisture and holds it. Synthetics trap heat.

Cool wool is not lighter wool. It is engineered wool.

Designing such fabrics requires control over yarn twist, weave density, and finishing tension. Without fibre-stage understanding, “summer wool” becomes a label, not a solution.
