The 4F Men's Running Vest is an ultralight outer layer designed for running and training on warmer days, when protection without weight is key. A slim fit and standard hip length ensure an aerodynamic fit and complete freedom of movement. Breathable, water-repellent fabric effectively wicks moisture and reduces overheating , while protecting against sudden changes in the weather. PrimaLoft® Silver insulation offers high thermal comfort with minimal weight, retaining its properties even in damp conditions. A quick-drying 4FDry finish helps keep you dry during intense exertion, while the eco-friendly Bionic Finish® Eco coating (PFC-free) increases water and dirt resistance without compromising breathability. Practical details—zip pockets, reflective elements, and the ability to pack the vest into its internal pocket—make this reliable support for any distance, always ready for use.
