Have trialled these gloves for several months now. I work outdoors most days of the year and in all weathers. My gloves have to be flexible, waterproof, breathable, warm in winter and with a lining that doesn't come away every time you take them off (which is often for me). No such gloves exist. Believe me, I've tried. Ski gloves, for example, give me the warmth I need in winter but that throws flexibility out of the window! SEALSKINZ however, are the only gloves that tick all but one of these boxes. My fingers do get numb when it's very cold (U.K. temperatures of 0-3 degrees) but they're surprisingly breathable on warmer but wet days. They are ruddy expensive but worth it!
