The STREET HEAT.ZB provides heat at one level for up to 3.5 hours using robust lithium ion batteries which only weigh 30 g. They are concealed in the cuff of the glove and you can hardly feel them. The gloves’ heating system can be operated using a switch on the upper hand. The flame shaped LED light shows when the gloves are switched on (light is red). The supplied charger unit recharges the batteries. The STREET HEAT.ZB with low heating capacity was developed especially for hiking and walking. Only the best materials such as 4-way stretch and goatskin are used. The windproof ZA BLOCKER membrane also ensures warm hands; leash.
