Winter Cap Mask

[Windproof & Warm ]: The skull cap is composed of a windproof soft velvet lining, which can isolate the cold and provide you with excellent warmth in the worst weather conditions.
[Helmet friendly]: The inner lining of the helmet can be worn under the helmet to block dirt and sweat and keep it clean. Support machine wash.
[Fully wrapped] The cap can cover the entire ears and face
to protect the fragile ears from harm. It does not cause ear pain like earmuffs, and it is not easy to fall off.
