Not just blocking the sun, but letting heat escape
Coolia is a line of sun umbrellas specializing in heat shielding, launched in 2026 by KIZAWA, a Japanese umbrella brand established in 2017. It uses the radiative cooling material “Radi-Cool” and is designed not only to block sunlight but also to release heat accumulated in the fabric. Under the message “Not just blocking the sun, but letting heat escape,” the line includes the ultra-lightweight airia, the auto-open-and-close auto, the two-section nino, and the short-length long umbrella long+. Its products center on all-weather umbrellas designed to provide both heat and UV protection.
