This gets a 4, wish I could make it like 4.9, because the seams leak and the lower headband part has no waterproof lining.
As a wind stopper it is a 5, but I don't need one for 3 oz. I can wear a Micro Dome at 1 oz. and a plastic vegetable bag over my head for a wind stop. I was hoping that it would stop water as well, and I believe it would if the seams were not there.
So it goes in my box of stuff for special occasions, or an Xmas gift. I can't give it less than 4 because MH nowhere claims it is waterproof, it is well made as are all MH products I have dealt with, and it is light enough to be worth it … for my daughter.
