I have had this suit for about two years and it is completely waterproof and offers good cold-weather protection if you layer underneath. It is far superior to an Aerostich Darien that I had for several years previously. It is too heavy for summer wear or any time the temperature gets above about 24 degrees C. A few faults - the goretex liner is rather loose and it tends to get caught in the zipper (on the jacket). If you don't do up all the velcro fasteners in the front, it will allow some water through. The pants have a tendency to develop small rips along the seams which become holes. Although the pants have not leaked, given how much this suit cost, this is a rather annoying fault. All the velcro seems to be coming apart which could be a problem in the future.
