Afforded is a medical head-cooling cap set that heightens scalp-cooling efficiency and that fitted on to a user's head produces no pressuring feeling nor slips out of place. The cap set is constituted from a head-cooling cap, an inner cap, and an outer cap. Two first belts that are drawn out from either side of the outer-cap opening part and stretch to the exterior are linkable by a first fastener, and after the head has been passed into the opening and the outer cap has been donned, the belts can be fastened neck-area-forward by the fastener; meanwhile, two second belts that extend from alongside the rear part mid-brim and head front brim-ward are linkable by a second clasp, and after the head has been passed into the opening and the outer cap has been donned, the second belts can be fastened around the forehead by the clasp.

Embodiments of particle protection headwear apparatuses and use thereof are detailed herein. In general, embodiments of the present invention include a shield and a shroud which couple to, or are partially or wholly integral with, a hat. The shield extends downwardly from the hat and is typically embodied as part of the hat. Further, the shield is designed for a user to be able to look through it. The shroud is coupled to and extends downwardly from the shield and the hat. The shroud extends entirely around a perimeter of the hat to form a breathable barrier between particles and the user's head. The shroud may be removeable from the shield and washable.

A headpiece includes a shell, a thermoelectric cooler, a heat sink and a fan. The shell defines a concavity. The thermoelectric cooler includes a cooling surface and a warming surface. The heat sink is in thermal communication with the warming surface. The fan is in fluid communication with the heat sink.

A water dispensing hat is provided. The device includes a hat member having a crown portion and a bill affixed along a front edge of the crown portion. A pair of reservoirs are affixed to an upper side of the crown portion on opposing lateral sides thereof, wherein each reservoir includes an inlet providing access to an interior volume. Tubing extends from each reservoir to a lower edge of the crown portion, wherein the tubing is in fluid communication with the interior volume. The tubing terminates in a dispenser housing affixed to a lateral edge of the bill, wherein each dispenser housing includes a nozzle on an interior side and a button on an exterior side. The nozzle is in fluid communication with the tubing and the associated reservoir. Upon actuation of the button, fluid disposed within the associated reservoir passes through the tubing and is disposed through the nozzle.
