Foam piece attached to a clip that slides onto the inside of the hat to keep head cool. is disclosed.

Headwear in the nature of hats and caps may be made with openings through an outside surface, near a lower edge of the rim. These openings admit small items through the crown of the hat and allow the items to rest in a crease between the crown material and a headband inside the hat. This provides convenient storage in the hat without allowing the stored items to come into contact with the wearer's hair or head. The simple structure, where items are in direct contact with both the inner surface of the crown material and the outer surface of the headband, facilitate efficient manufacturing (methods of which are also described and claimed).

A removable cooling apparatus for a hat spaces a headband of the hat away from a wearer's head, creating an air gap that allows air flow over the wearer's head. A removable cooling apparatus uses coupling structures to hold the removable cooling apparatus in place against the headband. The removable cooling apparatus can be removed completely from the hat when not needed or for cleaning, leaving the hat in an unaltered state. A removable cooling apparatus may use a thin flexible strip to keep the headband of the hat from falling open into the air gap created by the removable cooling apparatus. The removable cooling apparatus use compressible pads to space the headband away from the wearer's head. The contact location of the compressible pads with the wearer's head can be easily adjusted by the wearer.

A frame for a lightweight costume with air permeability, the costume, and a method for manufacturing them. The frame body for the costume includes a main body made of synthetic resin and a plurality of through holes penetrating the main body. The method includes a mold installation step of installing a mold in a predetermined three-dimensional shape on an elevating table, a resin member mounting step of mounting a resin member on a pedestal, a cover mounting step of mounting a cover covering the surface of the resin member on the pedestal, a heating step of heating the resin member and the cover, a vacuum molding step of bringing the mold into contact with the back surface of the resin member and then depressurizing the inside of the chamber, and a mold release step of releasing the frame body and the cover from the mold.

A spacer includes: projections each of which has a frame; multiple standing portions each of which has one end connected to the frame and that stand on the frame; and a standing-end connector that connects other ends of the standing portions, the frames being disposed close to each other such that the projections are connected; and flexible connectors that connect the frames. The projections have a three-dimensional shape. The flexible connectors are elastically deformable. At least either the projections or the flexible connectors have different shapes depending on a part of the spacer.

Medical gas delivery devices are provided. A garment or another object may include a hose assembly configured to couple the garment or the object to a medical gas source. The garment or the object can be configured to deliver a medical gas to a patient. Additionally, medical gas delivery devices configured to be removably coupled to a garment or another object are provided.
