Abstract: A multifunctional forearm band incorporating modulated airflow control to regulate temperature and moisture of a user's lower arm, hand, and fingers. The forearm band has a tubular member with openings at a first and a second end thereof. The forearm band can encapsulate or cover the lower arm in a first position and the lower arm, fingers, and hand in a second position. The second end can include at least one storage cavity, while the first end includes a first cavity for encapsulating the fingers and a second cavity for encapsulating the thumb when the forearm band is used in the second position. The user can open and close the opening in the first end of the tubular member to permit or restrict airflow or fluid flow across the lower arm, fingers, and hand allowing fully modulated airflow and fluid flow control to regulate the temperature and moisture about the lower arm, fingers, and hand.
