Recommended for outdoor work and leisure activities. This water-cooled vest directly cools the body with cold water. It uses frozen ice packs or ice to cool the water, then circulates it through tubes and a pump inside the vest to cool the body. For those who find air-conditioned clothing noisy, this vest is perfect. The quiet motor noise is unobtrusive. Simply replace the frozen ice packs or ice to easily restore the cooling sensation. The cooling tubes cover a wide area, even around the armpits.
