    I know what you're thinking: "Did he fire six shots or only five?" "Is that a Smith & Wesson 686+ 7 shot or 627 8 shot?" "Does he have a concealed Sig P226 SCT and two spare mags?" You've got to ask yourself one question: "Do I feel lucky?" Well, do ya, punk?

    I definitely could have used one of those summer time last year when I was working the afternoon shift (3pm-11pm) but I have no need for one now that I'm working overnights (11pm-7am)

    It would be very nice if they could work this into the military attire while in heat-hot areas!

    Ice bags are very BAD. (see below)

    FYI - These Cool Vests are the real deal, no joke, try one and you'll be amazed. I thought they were for sissies until I tried the smaller Cool Armor and then the Concealable Cool Vest during an all day Grand-Am DP racecar test session in 100F heat where I was driving 2 hour stints in a closed cockpit car with temps inside the car well above 120F. ALMOST ZERO PERSPIRATION AND NO HEAT STRESS! I was wearing a 3 layer Nomex racing suit over a layer of Nomex underwear, Nomex socks, boots, gloves, balaclava and helmet. I felt like a million bucks, other drivers (and some crew members) had to go in the air conditioned bus, lay down and drink water. We also use Cool Shirts and Cool Air systems in the cars and in the paddock for the crew, ( http://www.coolshirt.net/ )but they get too cold and are big contraptions with ice chests, lots of plumbing, switches, pumps, and/or blowers. AND..... they get too cold so you're constantly turning them on and off.

    "RPCM Cool Vests maintain a comfortable 59F, while ice or gel based systems are too cold at 32F or less.

    HOW THE BODY COOLS

    About 90 percent of the body’s heat is produced in the torso area by the major organs and muscle groups. The amount of heat generated is increased as the body works harder. In order to maintain a constant core temperature, the body must either give up or retain this heat as necessary. How this is accomplished depends greatly on the ambient temperature and humidity around you.

    Convective body cooling.

    Under normal conditions (60 to 80 F ambient temperature),
    the circulatory system carries core heat toward the skin’s surface.
    Since heat always travels from hot to cold, rather than from cold to
    hot, the body heat is carried away as the cooler outside air passes
    over the skin. This process is known as convective cooling, since the
    heat is removed by the movement of air.

    Evaporative body cooling.

    As the temperature outside begins to rise, the difference between
    normal skin temperature (90 F) and the ambient temperature narrows.
    This difference is known as the delta T. As the ambient temperature
    rises above 80 F, the delta T is not great enough to allow the body’s
    internal heat to flow away from the body by convection.

    Instead, the body reacts by cooling itself through
    a process known as evaporative cooling. When water fluid is exposed
    to warm, dry air, it will evaporate into water vapor. This change of
    state is called a phase change and it produces a tremendous cooling
    effect. The body creates this phase change by secreting perspiration
    from our sweat glands to the surface of the skin.

    When the air surrounding the skin is warm and dry,
    this is an extremely efficient process. But as the humidity rises,
    perspiration can no longer evaporate to water vapor, as the air is
    already saturated. This is a dangerous condition, since the body has
    no other natural mechanism to give up heat.

    Vasoconstriction and the brain.

    When the outside temperature drops below 60 F, the body needs
    to reverse the process and retain its internally generated heat. This
    is accomplished by a process called vasoconstriction. Vasoconstriction
    is the restriction of blood flow to the skin surface by contraction
    of blood vessels. Since the body’s organs must always have a flow of
    blood, vasoconstriction is applied only to those vessels carrying heat
    to the skin’s surface.

    When the brain is fooled into thinking the temperature
    is cool–for example, when ice is applied to the body–vasoconstriction
    occurs in an effort to prevent loss of heat, even though the core temperature
    is actually rising. This can lead to dizziness and fainting.

    More dangerous is the fact that the cool skin
    temperature physiologically feels comfortable, so you may actually
    work harder, creating an even faster rise in core body temperature
    and the risk of cardiac arrest."

    Thanks for the timely link, reinhold. I had a bout with heat exhaustion yesterday, so I just ordered one of those vests. It should be here by Thursday. I work outdoors in Florida doing tree work. Never had any problems before, but I guess I'm not as young as I used to be. It hit me hard yesterday, to the point of being scary.

    We have them at my FD for use in Hazmat suits. It works for us for about an hour. With heat indexes over 100 degrees now here, they make a huge differrene in how long we can work, but they add an extra layer when they "thaw", and a little more weight.

    Seems like a clever idea for emergency work. How many 'minutes' to recharge?
