I've been using the element mitten (about the same as the scout I guess, except different liner) for about 3 weeks now. And it's been pretty much perfect in temps between -10 and -20 celsius (15 and -5 fahrenheit), they've got a pipe glove as a liner instead of a fleece thingy, but I think the fleece thingy might be warmer. Atleast the DKdry stuff seems solid in cold weather, don't know how they are it if they get all wet though, but I wouldn't use mittens in wet (hotter) conditions anyway..
