Very good product, light, strong (actually flexible, which prevents breakage) does not take the moisture, does not interfere at all visibility. I was hesitant to buy it because there are unbranded for half the price, but I do not regret it. This mask follows the strict constraints of an uncompromising European standard, which makes the difference especially in cases of shock or accident and in comfort. I bike uses either when it rains or when it's cold, it's a joy.
