Built for cold-weather running, the Core Run Thermal Reversible Vest for Men combines PrimaLoft® Gold insulation for lightweight warmth with a wind-blocking, water-repellent shell for reliable protection. Designed with two functional wearing options, this insulated running vest adapts to any condition—choose the sleek Classic Look for everyday comfort or reverse it to the Night-Ready Look for enhanced visibility during low-light runs. Secure zippered pockets keep essentials close, while reflective accents on both sides add safety and style to every stride.
