Our new Frostie II gloves have been completely redesigned for optimal fit, comfort and performance. The focus on the styling of the Frostie II was to design a lightweight, all purpose glove that would provide maximum heat output and coverage while also eliminating any excess bulkiness. We believe we checked all the boxes with the Frosite II gloves. We accomplished this by developing a new ultra slim and lightweight battery that could be stored in a pocket on the underside of the cuff. With this new battery and location, the battery is almost completely unnoticeable to the user. Weighing less than 3 ounces and less than a 1/2 inch thick, this new battery tucks discreetly inside a waterproof zippered pocket where it hidden and ready to provide maximum power. What makes it so powerful? We used higher voltage battery cells allowing the battery to provide 8.7v of output. More voltage equals more heat. Performance Like all of our heated gloves, the Frostie II gloves are integrated with our patented Zero Layer Heating System that provides full heat coverage that surrounds the hands in cocoon of warmth. What does full heat coverage mean? Our heating elements extend the length of each finger and fingertip, the back of the hand and unlike our competitors, we also heat the underside of the fingers and the palm as well. Oh, and by the way, we added 20% more heating element coverage to these areas. You're welcome. Each pair of gloves includes two 2500mah rechargeable batteries and a dual charger. Simply charge up the batteries (light on the charger will turn from red to green to indicate a full charge) and connect each battery to the round plug found in the battery pocket on the glove. When you are ready for heat just press and hold the rubberized controller switch sewn into the glove on the back of the hand. Choose from 3 power level setting, Red = High, Blue = Medium and Green = Low. Approximate run time with fully charged batteries listed below. Batteries fully charge in 3-4 hours. High = 2+ hours Medium = 3+ hours Low = 4.5+ hours We are not going to post temperature recordings for this style of glove because there are just too many variables and we find that it can be confusing for some customers. Just remember though if you are planning on doing any comparisons, our gloves are made to be hotter than our competitors and our medium setting is typically higher than other's highest setting.
