So chill. Conquer the heat and keep cool with the AlphaCool Frosty Ice Vest. Constructed of mesh fabric with a beefy front zipper, the Frosty Ice Vest's three pockets (two chest, one back) hold large gel pads that quickly chill in your freezer or refrigerator. Replacement ice packs are included so you can cool down with one set while another set stays chilled. From AlphaCool.
