A cooling vest keeps the body cool during heavy work in the heat and helps prevent overheating, fatigue and loss of concentration. Ventilated versions use built-in fans to blow a constant airflow across the body, so sweat evaporates faster and your core temperature drops. Construction workers, welders and warehouse staff wear them on hot days under or instead of an ordinary work jacket.
The fans run on a compact battery, usually in the 10.8 to 18V range, with several speeds to match the airflow to conditions. When choosing, look at the fit, the number of fans and whether the battery and charger are included, because many models are supplied bare so you keep using an existing battery. A good fit makes sure the air circulates properly instead of escaping along the openings.
Pick a cooling vest that suits the working conditions and the battery platform you already run, so the cooling lasts the whole working day and you stay comfortable in the heat.
