Heat

Ok, So its like 92 deg and 85% humidity. how do you guys not sweat your butts off?

Have a very large butt.

I was just wondering if you all had any ideas of keeping cooler, or not sweating your kilts out.

Yeah; in the heat, cotton drawers are more comfortable than reggie.
A rub of something like Secret invisible antiperspirant between the thighs helps a little.
If you must wear hose, get really cheap thin ones. I've got some from Sport Kilts that are (relatively) quite comfortable yet presentable.
Avoid having to wear a jacket if at all possible. As a piper, I can't always do that, so I at least minimize the amount of time I wear it to only when I'm being paid to.
I find so-called Jacobite shirts to be a lot hotter than a short-sleeve Oxford, tropical uniform shirt, or polo shirt.
Situational awareness; always know where the shade is. Go stand in it; it's amazing how much cooler you'll feel.
Hydrate, hydrate, hydrate.
Always at least air out/air dry your kilts before hanging them back up in the closet, perhaps folding a dryer sheet into it when you clip it into the hanger.

Hydrate, hydrate, hydrate.

What he said! first, last, and always.

Be like these guys (intelligent):

Hydrate, hydrate, hydrate.

Poly-cotton! I did an 11-mile, 3,000' elevation gain hike on Thursday, temps in the low 90's most of the day (which is really unusual for this area). 5.5 yard poly-cotton desert camo kilt and 25+ pound pack. My t-shirt was soaked for most of the day, but I was cool and comfortable elsewhere. Body glide!
