The ice vest totally worked. I feel better than I have felt since I returned to NYC, even though I had a full day.
I wore it for 3 hrs running errands in the morning and in in to the studio. Refroze the ice packs (though I don’t think they fully froze b/c they were stacked on top of each other…). Then I wore it to meet BH for lemonade, ride the subway to chinatown, get a massage, and then eat dinner. After about 4 hours, all the umph was gone from the packs, so I took it off for the last ride home.
Frankly, I think everyone who gets overheated should be wearing one of these during the summer here.
