The ACTIADAPT™ collection was designed based on body thermo-mapping proven by the ASICS® Institute of Sport Science. This technology combines a structure that properly controls temperature inside the garment with moisture-wicking and quick-drying materials to help improve comfort from post-workout body temperature changes. The ACTIADAPT™ PACKABLE JACKET features a fine thermal fabric that feels extra comfortable against your skin. The fine loft texture helps provide just enough air to flow through to release excess heat and humidity while controlling temperature inside the garment. Welted front zippered pockets can be used for convenient storage for smaller accessories. Meanwhile, the zippered pocket features a packable design that allows the jacket to be rolled up and used as a pillow. The garment also includes a water-repellent and quick-drying fabric to help you keep dry and comfortable during activities.
