Heard of it? Tried it? Want it? How long has it been available? It looks like it could be worth trying, I have a short (but decent walk, whens its nippy out) to my beach, and it's always good to keep muscles warm as your heading out and its cold and windy. I use jackets before or sweatshirts, but they can be cumbersome and wet....
dont waste your money. wear a towel and jog. that way your muscles get warmed up for the session, and you have a towel to cover you on the way home.
Its a cool concept... if you have a prob with keeping warm you should invest in maybe say a ski jacket, which costs half as much sometimes, waterproof, nice and toasty and you can wear it when your not surfing. I dont know, personally i wouldnt waste my meager funds on it. here is a link for a water proof jacket http://www.llbean.com/webapp/wcs/stores/servlet/CategoryDisplay?page=trail-model-rain-jacket&categoryId=39677&storeId=1&catalogId=1&langId=-1&parentCategory=504721&cat4=504714&shop_method=pp&feat=593-sub1&np=Y
