Alright, thin and light, for light (not too cold) applications, but not for serious thermal protection. If, like me, you want to keep your fingers from freezing in under 30 degree temperatures for extended periods outdoors, even with good leather gloves on, get the Dakine Men's Storm Glove liners. Riding a motorcycle or snowmobile in the cold was not appreciably helped by these, while the Dakine's are perfect.
