Good points Bruce, but protection from the elements must include NOT getting heat stroke. I've rarely seen riders on tour from Northern EU or Canada to EVER get the gear thing right for truly HOT weather riding. Most end up stripping off ALL their gear or sending it home. And why do they always pick BLACK? Poor choice. Light colors are best when possible.

IMO, just can't use the "one riding suit does it all" approach. Textile stuff that "breathes" won't be enough. So called "breathable" fabrics really only work in the COLD, NOT the heat. It will Par Boil you unless it's flowing A LOT of Air.
Also, most built in armor does NOT stay in correct position for protection in a fall. Separate, strap-on armor is better, IMO.

The stuff I've seen a lot of Euro riders and Canadians wearing would survive a Canadian Winter. Yet, this is the same stuff many show up with in Cent. America. That's just insane.

It's a lot easier to layer up and put on a rain jacket than it is cooling off when you've got a poorly breathing, heavy duty Textile Jacket.

Fact is ... you need a WHOLE different approach to be comfortable .. and safe. Using proper hot weather dirt bike gear with GOOD armor is what works. Pack your Black Winter stuff away ... or leave it home.

I grew up riding the Mojave Desert, started riding dirt bikes in Mexico at age 13. A big hunky Enduro jacket with a few vents ain't gonna do it, especially if working hard riding off road.

Full flow mesh with high tech wicking base layers works. Dirt bike elbow and knee armor works, stays in position. Add back protection or some variation of this depending on your ability to manage risk.

When you gain altitude and things cool, add a base layer or two and put on your rain jacket. Unless it gets below freezing ... you will be OK in most situations ... and you'll do MUCH better in super heat/humidity ... which is NEVER easy.
