Cold Chills when temp over 100

As for sweating, as you ride much of it will evaporate. When I stop riding on a hot day, I will be soaked within minutes.

But I've heard and experienced that about sunblock, especially if you apply it heavily. It can really contribute to overheating. I can't stand sunblock for many reasons, so I'm really, really glad to have the arm coolers. They work wonderfully, I just wish they fit me better, which is why I'm shopping for a different pair.

Thank you all for your wonderful help. Here I was thinking it was a sunscreen issue and turns out it's much more serious than that. Both times when this happened I felt fine - so the thought of heat exhaustion never entered my mind.

However, when I was a teen I had an episode that while not exactly heat stroke was very close. 2 times after that I ended up in situations that were not nearly as bad, but still got dizzy and not feeling well (once on horseback and once setting up an event in the sun). Since I felt perfectly fine on the bike other than the chills, I guess it just never occured to me.

When we were in Hawaii, and then on a 75 mile ride during the summer, I always had a Camelback on me filled with ice and drink. That must have helped me cool down (and drink more often since it was cold).

Thanks again for the suggestions - I'll look at the wings and other things mentioned. And I'll make sure to pay closer attention when the temp rise up.

I have the short sleeve version. I really like the jersey. Very straightforward. Cut is a bit more relaxed then some. Cooler than all but one no sleeve white jersey that I wear. I just wore it this morning in San Antonio when it was in the low 80s and humid. Was nice.

I've been reading this thread with great interest as I do like to ride in the heat (for some odd reason). I can't, however, wrap my brain around the idea that sleeves help us to stay cool I am probably being much too literal, but it sounds like arm coolers have helped some of you...

They're white, so they keep the sun off, and turn solar radiation into heat less than skin tone does, even fairer skin. They're some super duper wicking fabric, which is why someone mentioned they have to be skin tight, so they enhance evaporative cooling (either from sweat or in drier climates, from water you pour on them). Even at worst, in hot and humid weather, they're no hotter than bare arms (trust me, I've tried both ways when it's been 90° and humid), so at least they prevent sunburn, which lotions definitely keep you from sweating and for that reason alone aren't very safe when it's hot.

I'm not sure how much of a cooling effect the sleeves add at cycling speed. With the air flow you get at even moderate speed, it has to be pretty dang humid before bare skin drips with sweat. On the bike, I mainly use them just to keep the sun off. I really notice the cooling effect running at lower temperatures. When it's in the 70s it's pretty hot to be running with bare skin, but the sleeves make it really comfortable.

I wore sleeves on a ride in Death Valley and they were awesome. In Michigan...not so much. It's too damned humid here, so they don't provide the same evaporative cooling. They actually make me feel hotter here. I think if a person lives in a desert environment that they'd be wonderful.

I've had that so-hot-that-I'm-chilled thing. It sucks...especially while running, since it's harder to carry adequate water.
