A neck scarf which a person can wear to keep himself cool in summer and warm in winter. The scarfs elongated mid-section defines a series of generally rectangular pockets, odd in number, arrayed end-to-end longitudinally for substantially the mid-sections entire length. A single gel pack is slip-fitted into each pocket, which is then sealed shut. Also preparatory to use, each gel pack must be activated: cooling gel packs by placing them in a freezer warming gel packs by heating them in a microwave. Disposed generally symmetrically about its center pocket, the scarf includes tapered end closure sections used not only to fasten the mid-section snugly about the neck but also to insure the center pockets gel pack is worn close enough to the hypothalamus to stimulate it, thus magnifying for hours the scarfs effect on its regulation of the bodys temperature.
