SAYSKY is expanding its Flow performance line for Autumn/Winter 2026 with new technical layers and water-reactive fabric designed for changing running conditions.

Launching September 24, the first release includes the new beige Flow Insulated Jacket and blue versions of the Flow singlet and T-shirt. The tops feature an all-over Running Couture print that reacts to water, changing appearance as the fabric gets wet.

The update brings a more visible technical element to Flow, SAYSKY’s lightweight, breathable and quick-drying performance range. While the singlet and T-shirt maintain the collection’s focus on speed and ventilation, the insulated jacket adds warmth for colder training without the weight of traditional outerwear.
