Note: The package contains 2* caps. Sewn fabric design, warm and breathable. The hat's fabric is spliced; the top of the head and the back of the head are made of black fleece, which is more breathable, so you no longer need to worry about sweating. The windproof, thickened fleece material around the forehead and head circumference provides extra warmth. Perfect for Helmets Do you shiver or still fear headaches from cold wind while cycling in the harsh winter? Even though your head is protected by a helmet, it can still feel cold in the freezing winter. At this point, you need the ROCKBROS Thermal Hat, designed to perfectly fit under helmets.
