Yeah, to clarify, I know what the rule is there for, I was just curious how to fight frostbite with two layers.
About three years ago at a tourney, it was below freezing, and in only our second game I became soaking wet from the pond that was in the middle of the field. You could easily bunker out the center, but it required sloshing through the edge of the pond. My dumb-ass about developed hypothermia, I had to run to the truck between the rest of the games to keep some heat in me.
