My wife and I both share the same frustration with the Keis gloves, and that is the independent controls on the back of the hand. It makes it quite awkward to adjust the left hand when you’re riding. I press it against the end of the handlebar, so I don’t have to take my right hand off the throttle. I much preferred how my old Gerbing gloves did it, where the heat output was adjusted by the remote controller, however, they were not the best gloves in the world.
I saw that Keis now do heated socks, but I’ve no idea how the hell you’re meant to adjust them when there’s a separate control on each leg.
I find that, certainly with the gloves, I’m constantly adjusting the temperature as I go from residential speeds to much faster speeds. I need to increase the heating output to compensate for the wind chill. Maybe it’s not quite as drastic of a change for socks.
