Therm-Ic, the true expert of electrically heated accessories, presents the new Boost range. Boost models warm up faster, and to a higher temperature than basic models, and their batteries have shorter charging times. The heat elements are much larger than those of basic ones, wrapping around your fingers and back of hand. The Boost gloves contain ample amounts of recycled fibers. As is expected, the batteries sit snugly in waterproof pockets in the cuff, and you'll find easy to use operating buttons near on the top. At lower power settings the effect is somewhat mild, and is based on boosting your body's own circulation. - Three power settings, with a max. running time of up to 10 hours at the lowest setting. - Surface fabric: 73% recycled polyester, 7% elastane, 20% polyurethane - Surface material: waterproof, hydrostatic head 10 000 mm - High quality Primaloft insulation, with 90% recycled polyester - Liner: 72% polyester, 28% recycled polyester - Palm with leather reinforcements
