Just a battery powered fan? Trying to stay cool as I’ll be wearing a costume against the Raiders and without a fan I’ll probably stroke lol I need to stay cool so lots of water (already checked and it seems you can bring factory sealed bottled water under 20 oz) and a fan seems like the way to do it.
It’s not even that hot right now. Drink water, wear sunscreen, suck it up
Man… I put the costume on last night in my air conditioned living room and was sweating lol. No need for sunscreen when all of my skin is covered.
