Great wetsuit for the cold winter water in Northern California%
My son says this wetsuit, a Christmas present, has been keeping him warm in the waters off San Francisco. Also, the Cleanline Surf people included a little surprise present with the wetsuit. and it was delivered a day early. I am impressed with the service.
