I like mine cause I can wear them when its not so cold, and they keep me nice and comfy, or when its like -30 plus wind, and my hands are like ooooh im so nice and warm, but not too warm, i dont want to get sweaty.
Mine are pretty warm, but they are performance/ tight fit, so they won't have work at 30 below. My biggest complaint is that the grip wore off after only a few days.
The cobras are a great mitten. They are a little thicker and more durable than a pipe glove with more warmth. We have them at the lowest price on the internet
