The present invention generally lower the body temperature of the human body, has the effect of preventing heat stroke, moreover, to provide a labor time and does not interfere with the movement time of the active cold arms bags in the field. A tubular sleeve portion 10 having a length covering the A forearm and upper arm, along the longitudinal direction of the sleeve section 10 and the cold portion 20 is formed on the inner side and become a surface when it is bent upper limb and, cold-storage section 20 has a water retention. The front end of the sleeve portion 10, a tubular hand covering portion can cover the hands may be connected together. If the cold arms bag A them wear upper limb after it is squeezed lightly soaked in water, it is possible to cool the arteries and veins are running the upper extremity due to the effect of heat of vaporization. .BACKGROUND【課題】人体の体温を全体的に下げ、熱中症を予防する効果があり、しかも野外での労働時や運動時の活動を妨げることがない保冷腕袋を提供する。【解決手段】前腕と上腕を覆う長さを有する筒状の袖部10を有し、袖部10における長手方向に沿い、かつ上肢を曲げたときの内側となる面に保冷部20が形成されており、保冷部20は吸水保持性を有している。袖部10の前端には、手を覆うことができる筒状の手覆部を一体に接続してもよい。保冷腕袋Aを水に浸し軽く絞った後に上肢に着用すれば、気化熱の効果により上肢を走っている動脈と静脈を冷やすことができる。【選択図】図1
