Rechargeable Handheld Fan with Carabiner

Last summer, when I was commuting from Brooklyn to Washington Heights on the subway for work, I finally gave in to buying a portable fan. I don't know what took me so long, but I was immediately the source of all envy on the A train, and even once held the fan over the face of a baby which I think bounced me to the final level of Mario karma. This is a good thing to have on hand when August rolls around and you don't want to show up to the function looking like you fell into the Hudson.
