The Zanier heating technology is based on highly developed textile heating elements and unique control electronics. The robust lithium-ion batteries, weighing only 60 g, provide warmth on three different levels for up to 10 hours. They disappear invisibly and barely noticeably into the cuff of the Heat.ZX 3.0. The glove heating system is easy to use – with a switch directly on the battery. The flame-shaped light indicates the selected heating level (yellow, orange, red) and shines through the perforated outer material. The included USB charger recharges the batteries overnight. The glove heating system is durable and can withstand hard impacts. The model can also be used without heating. Only top-quality materials are used: finest goatskin leather, 4-way stretch for comfort, soft, lightweight, and warm ZA Loft insulation, and a ZA Tex membrane for dry hands.
