I'd posted a reply in another thread concerning motorcycle clothing useful for the almost unbearable summer heat and humidity. Here are just a few of the options available... that will make riding in this heat somewhat more comfortable :)

Veskimo Personal Cooling System combines a lightweight, breathable personal cooling vest that is worn under ones normal clothing, connected to a Hydration Backpack that is worn over ones clothing. The body cooling vest is supplied with ice water circulated from the backpack via a high efficiency battery powered pump.

SteeleVest is a patented cooling vest used by people facing extreme heat stress conditions in the military, utilities, hazardous waste cleanup, chemical, medical and other industrial environments. Frozen Thermo-strips; (starch-based gel ice packs which you can freeze over and over again in a household freezer) are simply inserted into the insulated body cooling vest, providing up to four hours of cooling vest comfort at a time. SteeleVest's construction and features provide numerous benefits. There are no mechanical parts or maintenance worries, and no electric, air or water supply is required. The cooling vest weighs only five pounds fully loaded. It conforms to one's body for a slim and comfortable fit, and can be customized to deliver just the body cooling one desires in a variety of conditions.
