Michael L.wrote a review of Castelli Diluvio Gloves on April 2, 2012
This glove will keep most cold weather commuters happy. I live in DC and never really find myself wishing for something warmer in the winter months.
The only thing worth mentioning that may be a turnoff for some is the sweat factor. The way these gloves keep you warm without being super bulky is that they simply don't let any heat out. That means the perspiration of your sweaty hands will remain in the glove as well. To me this is irrelevant because I shower when I get to work - if you don't, a simple hand washing will get rid of the sweaty feeling.
