It is often difficult to dry sports kits in a holder. Here, a portable sport kit box has an air circulation structure that assists in drying activewear or warming it before use. A false bottom distributes airflow in the box. Ducts are present in accessory holders. The tub walls have slots for holding the lid in a vertical plane to hang clothes on for initial draining. A drain plug drains water after washing activewear. A filter is mounted on a wall through which air enters or exits the box. The filter can be connected to an external fan powered by a vehicle or internal or external battery. A solar panel, internal heater or internal fan may be included.

A shoe care device processes shoes by circulating air. The shoe care device includes an inner cabinet that has an accommodation space configured to accommodate shoes therein, an inlet defined at a first portion of the accommodation space and configured to supply air to the accommodation space, and an outlet defined at a second portion of the accommodation space and configured to suction air from the accommodation space. The shoe care device includes an air supplier that is disposed at the lower portion of the inner cabinet and includes a connection path configured to provide air to the accommodation space to circulate the air between the inlet and the outlet, and a dehumidifying material disposed at the connection path. The dehumidifying material is disposed at an upper end of the air supplier, and an upper surface of the dehumidifying material is exposed through a bottom of the inner cabinet.
