Frequently Asked Questions
Find answers to common questions about PEARL iZUMi products.
-
In-R-Cool® is PEARL iZUMi's cooling fabric technology, engineered to combine moisture management with UPF sun protection so it helps regulate skin temperature and block UV on hot rides.
-
In-R-Cool® works through evaporation and sun management, not refrigeration: the fabric moves sweat to the surface where it evaporates and cools you, while reducing the solar load that UV and heat put on your skin.
-
Yes. In-R-Cool® fabrics carry a UPF rating, so they block UV while they cool, which is why they anchor much of our Sun Protection lineup.
-
You'll find In-R-Cool® across hot-weather gear: jerseys, sun sleeves, mesh tops, and caps, the pieces built for the hottest, sunniest rides.
-
In-R-Cool® is engineered to actively manage both heat and UV, pairing cooling with UPF sun protection in one fabric. See how it fits within our broader Advanced Cooling range.
-
Wash In-R-Cool® gear cold, skip fabric softener (it clogs the wicking and cooling fibers), and air-dry to keep the fabric performing as designed.
