Looking for that all purpose heated vest that you take everywhere with you? This is the heated vest for you. Wear it as a mid layer underneath an outer jacket or on its own. The Carbon heated fleece vest from Volt provides shelter without sacrificing performance or comfort. Constructed with our Klimate Shield performance fleece that blocks wind through a special knit construction and a durable water repellency coating to help keep you dry. The outer anti-pilling and four-way stretchable fleece is bonded to an inner layer that uses a high density configuration for wind-blocking, water resistance but allows for superior breathability. And on top of this we added our patented Zero Layer Heat System that has heating panels strategically placed in 4 zones and 200 grams of core insulation that surrounds you in a cocoon of warmth. What's left to add? We are including with the vest our VB5TEN rechargeable USB battery that will provide 5 - 10 hours of heat on single charge depending on your power level setting.
