I picked up these gloves for my winter motorcycle rides, and they're just what I needed. While they're not as hot as the plug-in heated ones, they definitely keep my hands warm during chilly rides. I've tested them in temperatures below 40 degrees Fahrenheit, and they've performed admirably. My daily commute on the bike is over an hour, and these gloves have been fantastic. They're slightly bulky, but it hasn't been a problem for me—I can still operate all the controls on my bike without any issues. Overall, I'm really pleased with them!
