I'd like some of your thoughts on an idea I had while suffering under the sun this past Saturday.
I don't perform well in heat, and with a multitude of crits happening at the peak of summer here, I'd like to do more to help my body keep cool. What do y'all think about freezing a bladder full of water in the Racebak and wearing it under my skinsuit? It's additional weight, and in a flat crit with lots of micro-bursts that weight will probably cause me to work a little bit more, but I'm hoping the lower core temperature and (hopefully) better performance are worth the cost. Thoughts?
The point here is not to use the Racebak as a replacement for water bottles, but to help cool my body by basically putting a block of ice (the frozen bladder) on my back. Think of it as a poor man's ice vest.
