Genuine product This is an insulation cap with padding in the ear flaps. The outer fabric uses lightweight recycled ripstop nylon, and synthetic fiber padding is only inserted in the ear flaps. Furthermore, a brushed material is used for the lining to improve heat retention. Darts are added to the ear flaps, creating a design that is less susceptible to wind resistance even when the ear flaps are raised. Function Padding (ear flaps) Free shipping via Yu-Packet (within 3cm), and it will be folded in half for shipping due to size constraints. Shipped via Yuu Yuu Mercari service. Sorry, but the price is not negotiable.
