Can a team wear a leg compression sleeve for any reason?

A team can wear a leg compression sleeve only for medical reasons. The rules established by NFHS require that any apparel worn by players, including compression sleeves, must have a legitimate purpose related to the player's health or injury management. This means that if a player has a medical condition or is recovering from an injury, wearing a compression sleeve is permissible as it can provide support or improve circulation.

In contrast, if a player is wearing a compression sleeve merely for aesthetic purposes or fashion, that would not align with the regulations. The governing body is focused on ensuring that all uniform items are consistent with the spirit of fair play, and that player safety is prioritized. Other options are incorrect primarily because wearing a sleeve without a medical justification or during warm-ups does not comply with the established guidelines, which restrict apparel to medically necessary items.
