Hi! I've been windsurfing for over 25years and am still mad for it. I sail all year in all temperatures but like everyone else I battle with cold hands during the winter months. Well, not anymore! I have invented and launched a wetsuit incorporating a breath powdered hand heating system which allows me to enjoy my windsurfing in all weathers making the most of winters better winds and waves. The hand heating system integrates with palm-less mittens, but you can cut away all of the underneath of the mitten so that there is nothing between your palm or fingers on the boom so that you grip is not disturbed. The wetsuit is called Ianovated - have a look at it at ianovated.co.uk - it could change your winter windsurfing!
