The Brain Shroud??? is a lightweight, close-fitting beanie, used for insulating under helmets and wicking sweat while you stay on the move. The Brain Shroud???'s thoughtful design includes a diverse construction: a single-layer fabric format sits on the crown of your head, while a double layer band is placed at the ears; allowing for you to release heat buildup without sacrificing warmth where it's needed. The low-profile and snug fit make this beanie ideal for wearing under a helmet or as a liner of any kind, while the style looks sleek as a stand-alone hat.
