The large neck (40-60cm, 16-24") wrap (shown) provides hot or cold pressure and immobilisation of the cervical spine region post surgery and trauma. The small neck (40-50cm, 16-20") wrap is narrower and of less robust construction but still provides cervical support and cooling. It can be worn during summer months as a means of keeping cool. The neck wrap can help tremendously with control of hot flushes, headache and raised temperatures. The neck tie is a small, 2-channel neck scarf worn by the sports person, gardener, walker, etc to help keep cool in summer.
