For this week’s installment of #RunOOTD, Illeana is decked out in a Reebok running look perfect for the upcoming chilly days of fall. Reebok’s ACTIVCHILL Tee ($40, reebok.com) is the perfect base layer because the engineered fabric pulls heat and sweat away from your skin to keep you comfortable—even after you start heating up well into your miles. The Long Legging by Reebok ($70, reebok.com) makes the perfect match for this outfit—and any outfit—while providing a slim fit that moves with you, reflective details, and Speedwick technology that keeps you cool and dry.

For those extra blustery days, Illeana keeps warm with Reebok’s Running Essentials Wind Jacket ($60, reebok.com) made with 100% recycled polyester (so you can feel good knowing your purchase has helped the environment) and features the same Speedwick technology, and 360-degree reflectivity for increased visibility. Finally, Reebok’s FloatRide Run ($150, reebok.com) completes the look, and ensures an extremely well cushioned and responsive ride. It also won Best Debut in our 2017 For those extra blustery—check out our full review of the FloatRide, here.
