Keeping cool under Kevlar

*From Beerio’s Manual
Keeping cool under many layers of Kevlar
There a few different methods for cooling in suits.
*One way is to put different types of cooling packs in the refridgerator and then stuff these packs in pockets in the inside of the suit.
*Another is to have tubes with water (salt water might be better to keep the water pure and keep it from turning green and slimy) running around the body on the inside of the suit.
*Last, and least effective, is to have holes and vents for ventilation.
