are there summer clothes designed to pull heat from your body?

Factual Questions
1

There are winter clothes designed to keep heat in like gloves, hats and coats but in summer all people do is try to wear as few clothes as possible so evaporation keeps them cold. That and go swimming, which helps evaporation.

But does anyone make clothes that are made of a lining that absorbs body heat? In winter people wear hats with linings made of cotton, does anyone make summer hats that have linings made out of a heat absorbing liquid?

Are there sprays you can put on the parts of your body where the most heat is passed (armpits, head, back of neck, groin) that will absorb heat? It seems like anti-perspirants are counterproductive in hot temperatures because they prevent sweating, which prevents evaporation. Are there underarm sprays that will pull heat out of those areas rather than just prevent sweating, keeping you cooler?

So my question is, are there summer clothes or chemicals that are designed to pull heat out of your body when its hot? Because i haven’t seen any before but it seems like such an obvious market. I’d wear a hat with a liquid coolant or ice liner if i thought it’d help.

There are fabrics that wick away sweat from your skin (in an effort to keep you cooler and drier). That’s kinda sorta what you might be looking for.

Coolmax and dri-weave are two that come to mind. I wear running shorts and shirts that are made of this, and it’s much cooler and lightweight than wearing cotton shirts.

Well, there is “Coolmax”, which is designed to wick sweat like crazy. Now, I ONLY wear briefs of Coolmax. Try it, and you’ll make the change.

Then, there are the little neck/bandanna thingees with water absorbing deeliebobs in them- they get wet, and stay cool & damp for hours.

One quibble- when you are cold- cotton is BAD. Wool is good. (Now there are some synthetics which rival wool)

Yes, there is a cool suit. However, there are drawbacks. It was used for a while by some NASCAR drivers before the teams got serious about ventilation. Here’s how it worked: It’s a mesh undershirt with a web of plastic tubing sewn on. The tubes are connected to a pump that runs to a cooler. The cooler has a coil of tubing at the bottom, under a pile of ice. The pump circulates a flow of cold water through the shirt, which absorbs heat from your body.

Now, for the drawbacks. It’s heavy. It’s too cold at first. When the ice is all melted, the meltwater cools down pretty quickly, and it stops being useful. The process had no temperature control, and no way to replenish the ice.

I’m sure inventive minds could improve on the original design, but in its original form, it was not worth the hassle.
