Good for a dry cold
These do exactly what they say, keep you warm. As long as it's dry they feel great. They're fleecy on the inside, so they're a bit like a nice pair of pajamas, but you go ride in them (by a second pair for sleeping). I live in the mountains and they work great in the 30-45 range, after that they get a little warm but are still wonderful. Not at all water resistant, but in the dry climes where it gets chilly, the southwest, they'll keep you going in base season. I'm 6'5" 155 and the large is a glove like fit and these actually run the entire length of my legs right down to my shoes, no more cold ankles!
