Now with smartphone control through the Lenz heat app the Lenz Men's Heat Glove 6.0 will have you comfortable in the cold as you’ve never been before. Light, breathable, and toasty warm these have a run time at 107 °F of 10-14 hours, longer than most mountains are running their lifts! Compatible with all the Lenz lithium packs use the batteries you have or add a new pair these give you a whole new appreciation for winter, no more numb and tingling fingers, no more fumbling with numb hands, no more coming in from the cold just to hold a cup of coffee so you can get back out there again. Make full use of your day when you don’t have to come in but can take run after carving run without concentrating on freezing fingers!
