Our Bambull® hat is warm, soft and very comfortable - in addition, it is guaranteed to be itchy! The hat is made with soft bamboo viscose on the inside and warm merino wool on the outside, so that no wool comes into direct contact with the skin. Ideal for people with sensitive skin who normally react to wool. The hat fits snugly around the head, and is perfect for an active day outdoors. It will fit nicely under the bicycle or slalom helmet, without compromising on comfort.
