Thank you for viewing! This is a cold-weather helmet inner cap (please note that the helmet is not included). The buttons are processed to be attached inside the inner cap so they are less visible. Also, during inspection, if the snap buttons are loose, we press the buttons again to reduce the looseness. Therefore, it may look like the 8th image, but there is no problem with use, so please rest assured. Size: Head circumference approximately 57-59cm Are you having trouble with your ears and head getting cold in the cold season, such as when riding a motorcycle or snowboarding? With half helmets and jet helmets, cold air can enter through the gaps, and it may not be comfortable while riding. This cap can wrap your entire head and keep you warm. The brim has a jumper hook that can be securely fixed to the inside of the helmet. It prevents slippage and flapping due to wind while riding, allowing you to wear it with peace of mind. It is ideal for those who love jet helmets and half helmets, as well as for winter sports, touring, commuting to school, etc. It has a simple design and is easy to use, and it can be folded compactly, making it easy to carry. Please consider it now as a cold weather measure. Thank you!
