“I haven’t tried them in subzero weather yet, but at about 30 degrees farenheit the medium is lust about perfect. The preheat feature uses quite a bit of battery, and I haven’t yet been out long enough in really cold weather to completely drain them. Colorado winter weather is highly variable, so I like the adjustability.
They fit well and are comfortable to wear with or without the heat on. The palm is grippy, but the grippy panel needs to be bigger.”
