I am not saying this because I bought one, but I had a Sun Ice and found that when we went over to Ireland and Scotland they did not hold up to the brutal November conditions that Zero Restrictions did. It is a very expensive product, but most are goretex and they are designed for golfers. They have pockets in the right places, the pants have pockets with zippers inside to access your pants or shorts. This product is an incredible product that kept me warm and dry in 45mph winds at Ballybunion...no exaggeration.
ps I am selling a large suit!
