Really disappointed with this after all the positive reviews. First, buy a size bigger than you normally would. Could also do with being longer as it's barely the length of my upper body. Finished the end of an hour sailing soaked through. Could feel water working its way through the fabric, as well as through the cuffs and bottom, despite tightening all the velcro straps.The one thing it has got going, is once the water is in, it does warm up quickly, so although soaked through, I was still reasonably warm on a 17?C day with just a polo shirt underneath. Would not recommend though, and not a patch on my old (unfortunately lost) spray top.
