It's probably a better idea to go to an ice cream shop in town and buy a slushy drink to take internally. Then fill up water bottles with ice and water and put that in your back pocket. After the ice melts, you can drink the water in the bottles.
I've always heard that you should place whatever you have that is cold (even cold running water) over the inside of your wrists and or neck. Thought being that these places are the two areas on your body that have the least amount of flesh between what's cold and your blood. End result being that you are "cooling your blood" quicker. Whether or not that is the truth I have no idea but it sounds clinical but more importantly, it feels dang good.
I remember those neck ties that you wet and then freeze and they end up lasting for hours staying cool. I saw that same technology applied to wrist bands....again, have no idea if it actually works but, it's an idea to investigate I would think.
