Details

Temperature regulation

ThermoShell™ combines thermal insulation with active ventilation through alternating fleece and mesh panels. The fleece retains body heat, while the open-knit areas promote airflow and moisture release. The result: consistent temperature regulation, even during sustained effort.

Sustainable Performance

ACT products are designed to meet the demands of running while reducing their environmental impact through bio-based materials, precise carbon-footprint measurement and optimised manufacturing choices.

100% Natural Bio-Polyester

The polyester used in ThermoShell™ is entirely bio-based, made from repurposed cocoa husks. This plant-based fibre offers the same performance as conventional polyester—strength, durability and heat retention—while making use of a previously unused natural resource.
