I've soaked a white Nike cap (olympic marathon style) and a vest in water and frozen them in my freezer.
They're like an ice helmet and bulletproof vest.
If I take them to the race tomorrow and put them on just before the gun, how much of an edge will this give me in hot conditions? Will I get an ice migraine and frostbite or have a big edge in hot weather. They'll defrost quickly.
Edge?
