Being a native and living all but 2 years of my life here, I'm pretty well acclimated, but even I pour sweat during summer treks. One liter of gatorade for every two liters of water seems to be the right ratio for me. A bandana is a must, it's the only way I can keep sweat out of my eyes. Underarmor base with a synthetic button up works pretty well for me, and for the most part I prefer pants year-round. Plenty of canopy in the backcountry so the sun isn't an issue. I'll gladly accept the humidity for the year-round mild weather. No down, snowshoes, ice picks or 0-degree rated bags needed here.
