I've been using a pair of neoprene
Chota's that are pretty good. I like the removable thumb and index finger feature. They are un-lined and need a liner in the cold. I bought some thin ski glove liners that work well under them - they sell them at any ski shop. Because of the removable finger option water will leak in if you dunk them, but I wouldn't want to give up the dexterity.
