Ice down your back when wearing robes outside

the ice down the back thing worked for me in florida. I actually have an idea for an "ice water tube networking" that runs from the base of your neck along your arms and out behind your feet. just need some pvc tubing a funnel and some duck tape lol. it would be cheaper.

edit: the sharper image things that go around your neck look interesting to say the least but I can't immagine that being comfortable
