The women's 4F Running Vest is an ultralight outer layer designed for running and training in warmer weather, where comfort, protection, and freedom of movement are key. A slim fit and standard hip length provide an aerodynamic fit and stability during activity. Breathable, water-repellent fabric effectively wicks moisture, prevents overheating , and protects in sudden changes in the weather. PrimaLoft® Silver insulation offers efficient warmth with minimal weight, retaining its properties even in damp conditions. A quick-drying 4FDry finish helps keep you dry during exercise, while the eco-friendly Bionic Finish® Eco (PFC-free) treatment increases water and dirt resistance without compromising breathability. Functional details—zip pockets, reflective elements, and the ability to pack the vest into its internal pocket—make it a reliable support for any distance.
