Ergodyne 41702 Rechargeable Heated Vest Medium Black

Product Description

The ERGODYNE 41702 is a rechargeable heated vest designed for workers and tradespeople operating in cold to extreme cold conditions. It includes a 7.2-volt, 5000 mAh battery power bank and delivers heat across four zones: neck collar, mid-back, left chest, and right chest. The vest features 80g of insulation and a wind-resistant polyester exterior with a fleece-lined collar. A stretchable spandex-blend side panel and elastic bungee waist provide a snug, athletic fit that keeps heating elements close to the body without restricting movement. Three heat settings provide runtimes of up to 9 hours on low, 5 hours on medium, and 2.5 hours on high.

This vest is built for use as a mid-layer in cold working environments including construction sites, transportation yards, warehouses, and outdoor utility work. Its low-bulk profile allows it to fit comfortably under heavier outer jackets and PPE. A waterproof temperature controller with a thermal protection shutoff prevents overheating. The integrated USB-C rechargeable battery pack includes a colored LED gauge for easy battery life monitoring. This vest is appropriate for professional tradespeople who need sustained warmth during extended outdoor or unheated-indoor shifts.

Installation Notes

No installation is required. Before first use, fully charge the battery pack via the included USB-C cable.

Follow the manufacturer's care and washing instructions before washing to avoid damaging heating elements or the battery connector.
