Hat, helmet, and other headgear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

A sportswear cooling system for enhancing physical activity for a wearer is provided which has a first compartment containing a cooling solution and a second compartment containing water. The first compartment is positioned within the second compartment and the walls of the first compartment are adapted to be ruptured so that when the cooling solution and water combine an endothermic reaction is produced calculated to cool a portion of the body upon application.

The invention relates to an arrangement that can be worn on the heads of members of a group. This arrangement comprises at least one banner (B1) with two side edges (B1a, B1b) and at least two items of headgear (K11, K12), each with at least one holding means (K11c, K12c) on an outside (K11b, K12b). The banner (B1) can be fixed on the holding means (K11c, K12c) via the side edges (B1a, B1b) in such a way that the items of headgear (K11, K12), and therefore also the members of the group wearing them, are connected to each other by the fabric (B1c) of the banner (B1).

An absorbent wristband apparatus is provided. In some embodiments, the apparatus may comprise a body with a first end and a second end. The body may be formed into a hollow cylindrical shape with a first opening at the first end and a second opening at the second end. A cavity may be disposed in the body and may be continuous between the opening at the first end and the opening at the second end. A first elastic element may be coupled at a first end of the body and a second elastic element may be coupled at a second end of the body. The apparatus may also comprise one or more fasteners such as a loop fastener and/or a button fastener which may preferably be coupled to the body proximate to an elastic element and/or proximate to an end.

A headlamp with frontal lamps and rear signaling is presented. The headlamp uses part of the light produced in the front lamp to achieve rear and/or lateral lighting and signaling. The headlamp has a housing which includes a light module, a light source and a holding strip for allowing the housing to be fixed to the head of a user. Tthe light module contains a module for connecting one or more optical fiber(s). The holding strip contains one or more optical fiber(s) having first and second ends. The first end is coupled to the connection module. The second end is coupled to at least one optical diffuser. A method of providing a headlamp with frontal lamps and rear signaling is also presented.

A face covering comprising a head attachment means, and a mouth and nose covering, wherein the mouth and nose covering includes a first internal face arranged in use to proximate the mouth and nose, and a second opposing external face arranged in use to be facing away from the mouth and nose, wherein the face covering is arranged to move from a first usage position to a second storage and transport position, characterised in that the head attachment means is arranged to secure onto the second face in the second position through a securement means.

A wearable headlight holder assembly includes a central rectangular webbing with two stretchable rings extending at distal ends, and a strip of Velcro sewed to the center of said webbing and used to detachably strap the webbing to a headband. The headlight holder assembly allows for the placement of a light source though the two stretchable rings and allows the user to illuminate a chosen area. The present design are more flexible to fit headlights with various sizes and cost-effective to manufacture. The flexible design also allows it to be attached to a headband, a clothing, belt, or forearm for uses including but not limited to exercising, repairs or camping.
