A heat exchange garment or a system is worn on a user's head for engaging the head area and having extensions for surrounding the neck. The garment comprises an inner layer and an outer layer. Substantially, the entire volume between the inner layer and the outer layer may be filled with heat exchange material. Alternatively, sections may be formed for retaining individual thermal packs, each in registration with a portion of the head area or neck.
