A polymer band 2 configured to form a loop with an internal face 4 that wraps around a body part. The band contains one or more pads 7 comprising a receptacle substantially made integral with the polymer material of the band 2. The receptacles (8, Fig 6) contain a thermal material capable of transferring thermal energy to and / or from the body part. The band can have complimentary fasteners 6 (e.g buttons or hook and loop) to allow adjustment and / or closing of the band 2 on the body part. The thermal material can be a liquid, solid or a gel, and can comprise water, a coolant material or a suitable material for heat transfer. The polymer material can comprise one of silicone, polyurethane, thermoplastic elastomer and/ or elastomer. The pads 7 can have a convex curvature towards the internal face 4 of the loop. Each pad 7 can be a spherical or elongated dome. The thermal material can be configured to be preheated or precooled prior to use.
