The hat I bought for the winter, because at -6 ° C, unfortunately, coat, scarf and gloves bring only little when the head is free. It is a knit, so it is not very thick and an icy wind they will not stop to let the head freeze, but I recommend doing a lot more properly thick fleece caps, or the one with love gehekelnten knitted grandma. A big benefit is the cap, however, for a person like me with a huge head usually has trouble with caps. In this Here I Come warm through the winter and have even a few cm square up what I have never been able to experience. My head is in itself but warm, so it's no problem for me, that the material is not properly sealed.
